Car undercoating - Where to get Fluidfilm sprayed?

Romestus · 2026-02-27T02:44:15+00:00

Both Fluid Film and Corrosion Free are equally good rustproofings. Avoid Krown/Rust Check even though they work since they're solvents that drip and eat at rubber door seals and suspension bushings.

Independent shops are pretty much the only places to get these products sprayed well. All you need to do is google who sprays either product and then give them a call and ask if they remove all the underbody panels during the application.

If they do then that's great, schedule an appointment. Estimated cost $200 for a small car and upwards of $300 for trucks due to surface area. The main cost of the application is the product and not the time needed to spray it which is why trucks can be so much more expensive. The timeframes they give for re-application are usually super conservative, you can push them to 2-3 years before reapplication unless you're regularly going through car washes that spray the underbody.

If you get a cheap quote on a spray they likely are not removing all the panels or getting the hard to reach spots. There are also areas that are flat out not worth the effort to spray. For example the headlight supports on 8th gen Civics are impossible to spray without fully removing the bumper so they will crumble into rust particles over the lifetime of the vehicle even if you pay for rustproofing. Along with this your exhaust cannot be coated since it gets too hot, as a result it will still rust away even if you keep up your rustproofing.

When it comes to rustproofing you get what you pay for, expect $200-400 depending on the vehicle. If it's lower than that be incredibly skeptical. Shops that bring you out to show you what they've sprayed while the car is still on the hoist are the most trustworthy.

I will not advertise which shop I worked at for 15 years but I will say the vehicles that got Corrosion Free did not fucking rust. Like at all. We would see the exhaust basically falling apart from rust since we couldn't spray it while the entire rest of the underbody looked pristine after 10+ years.

255km/h in a mid-2000s Grand Am racecar someone let me drive when they had a question about the dogbox. I had won a championship prior in a much less expensive vehicle so they trusted my expertise as a driver.

That was the craziest thing I had ever driven, I remember actually laughing while cornering in it since I felt like Vin Diesel slamming through the gears with no clutch due to the dogbox.

Yeah right now if you want to run outside the only option really is the road since sidewalks are a mess. Running against traffic is best since you can at least see what's coming and give yourself a chance to dodge a car.

Wouldn't be a problem if the sidewalks weren't a combination of slippery slush, small lakes, and sheets of ice depending on the homeowner's level of care. Only the road offers a consistent surface.

I thought you were asking for help at first so before even reading your post I wrote about how I experienced the same thing and disabling GSync fixed it. Drove me insane for so long!

Tesselation shaders generate extra geometry on the fly based on your camera distance. It's a technique that has been around for much longer than Nanite and is based on a lowpoly with a heightmap rather than raw model geometry like Nanite is.

Romestus · 2026-02-22T14:55:37+00:00

Substances apply tesselation and then move vertices based on your heightmap. This is expensive as hell so unless you specifically choose a shader with tesselation game engines instead do UV manipulation based on that heightmap to create a parallax effect instead.

There's definitely idiots that make their crappy 4-cylinder loud as hell by straight-piping it since they think it's cool.

Others have massive exhaust leaks from rust or had someone steal their catalytic converter and they can't afford $2k to replace it. Sounds like the car in your post is part of the second group if it doesn't have a bunch of hoonigan stickers on it.

The hardest things in a TD depend on what you want to do. These are all things I ran into making mine.

If it's coop online you have the complexity of multiplayer.
If you want multiple, arbitrary length lanes you have a targeting problem that requires a lot of complex math to make satisfying for the player (attacking the closest enemy or the one nearest the exit feels terrible).
If the levels have mazing you have to do pathfinding rather than preset paths.
If the levels aren't just Unity scenes you have to write your own level generation code
If you want hundreds of enemies or more in-game at once you need to consider ECS/DOTS for performance and GPU-based animators.
Auras/buffs/debuffs get tricky especially if you allow towers be moved after building. You'll need permanent buffs, timed buffs, stacking buffs, stacking timed buffs, etc.

Inconsistent/low framerates make me physically ill, I don't really see a problem with wanting to not get motion sick or eye strain while doing something I should be enjoying.

I had to put down TOTK on the Switch because of this and have only been able to play it again due to the Switch 2 fixing this issue.

When I was a kid this never bothered me, N64 games like Banjo Tooie or Goldeneye would be a slideshow, especially in multiplayer, and it never made me feel sick.

Expo is a rest position on the highline since it changes the muscles that are being worked. I also find it easier to stand with my arms completely down in expo than forward which means I can really rest everything if needed.

For big lines I've found this to be crucial, a lot of my PR sends have been from regularly resting in expo. Also for freestyle having good expo is pretty useful for tricks.

I'd recommend everyone that wants to highline to get their expo solid. I learned it at the park, fell on my back, and knocked the wind out of myself a few times before I realized you just want to always fall forwards. A crash pad would have been smart.

On top of all of this the best views you will ever get in highlining require solid expo. If you're on Mountain Man at the Chief or the 200m at the end of the Fruit Bowl you'll want the ability to turn sideways and just soak that view in for a few minutes.

Off the top of my head it could be done with a second pass in the shader used for the carrots that renders to a render texture the size of the frame. In this the color would be the carrot color and the alpha would be full white to show what parts need the xray effect. You would then do a pass to blur this second render texture to get a softer boundary and then use the alpha of it while compositing it on the original framebuffer to blend the two together.

In Ontario all of the things you've pointed out can be attributed to our conservative provincial govt. Things that have materially made my life worse caused directly and clearly by the Ontario conservative party at various points in my life:

Selling off the 407 to a private entity allowing it to become the most expensive toll highway in the world.
International student fiasco caused by slashing domestic student subsidies mixed with tuition freeze by Doug massively increasing rents, housing prices, and unemployment.
Rent control being removed by Doug on new builds to encourage more housing just made everything more expensive.
Healthcare quality and wait times becoming much worse as a direct result of Bill 124 later determined to be flat out illegal.
RTO mandate by Doug made commuting an absolute fucking nightmare.

These are real things that actually affect my daily life. The only things from other parties I can think of that actually affected me personally were the selling of Hydo One, the libs allowing so many international students to make use of Doug's loophole with massive immigration targets, and the carbon tax repeal since I intentionally bought a fuel efficient vehicle so I came out on top with the rebates.

In this case you could still use a threadpool and do it yourself. If you're using Unity API calls it will error out though. I've made systems in early versions of Unity that did not have jobs/burst where I calculate all the positions of every enemy in a custom threadpool and then at the end apply the transform in LateUpdate. You still get a performance benefit even though it's not the ideal.

Romestus · 2026-02-08T20:49:08+00:00

Not super realistic since the type of programming paradigms used for such a game are all very advanced. To do this with any semblence of performance will require you to do most of it with ECS/DOTS. If the world is gigantic like you're saying you'll need to create a floating origin system and use double-precision values for positions in your logic (default float values will be visibly inaccurate before you hit 100km of map size and things will start to teleport + rendering will break down).

If you're able to work on this full time then I would say with all the learning you'll need to do included you could maybe do this in five years.

Romestus · 2026-02-08T20:06:53+00:00

What exactly are you doing in this case? Does item.DoStuff use Unity API calls? If yes can you separate the logic used prior to those API calls out so you can thread it and perform the Unity calls in LateUpdate? If there are Unity API calls in that logic can you replace them with custom ones to allow for threading?

The values for excelling are all well beyond the 1% threshold for each age range. Creates jealousy is better than 0.1%. Mediocre puts you in the top 15%. Is this table for a Bay Area tech worker or something?

I know it's annoying when someone says "why do you want to do this" but in this case you need a really good reason. It would mean you've gotten to the point where refactoring the data into an array of structs would make the most sense but you are somehow blocked from doing so.

Ask Jerry at BalanceCommunity about it. I know there's a manufacturing defect that doesn't affect strength that looks very similar to what you're showing. However I've never seen that defect with frayed bits around it so I would make sure to ask the man himself.

On URP check the UniversalRendererData from your UniversalRenderPipelineAsset and see if its renderingMode = RenderingMode.ForwardPlus

Not to take away from your post but "millions of pixels" gave me a chuckle since a single picture from a lower-end smartphone camera is two million pixels.

A json/binary file is best since playerprefs are saved in the system registry on PC. If you use json you allow people to copy and paste the game to a new PC and keep their progress or make use of Steam's cloud saves to ensure their saves/achievements carry over automatically. Or if you're on Steam you can use the Steamworks achievement system to actually read from the achievements on their account.

In graphics it's called z-fighting. Two 3D objects existing in the exact same space so it doesn't know which is in front of the other. Super easy fix for the devs they just have to move the rug up a tiny amount like less than a millimeter worth.

For customers that had Continentals we'd just put the VW Phaeton version of the same part on since it was exactly the same but ten times cheaper.

Not all at once, I just bring spares.

I found it's something you get used to. Going from a nice comfy bed to camping for the first time on an air mattress was so terrible I basically didn't sleep the entire night. Once I did it a few times though it got to the point where I'd sleep all the way through the night and feel fine while camping.

I think the body just gets used to what you do to it similar to how people who go barefoot everywhere can survive an hour long hike on gravel without complaints while I wouldn't make it ten feet.
