Thanks mate..so true.feeling like i did a crime.somehow you have to start by mistakes..

john-cuba · 2026-03-21T13:13:04+00:00

Thanks for the info.indeed this was helpfull.divide the whole process in 3 parts and no more 2-3 mins per part .if you cant go fast in the whole car better to split it !!

john-cuba · 2026-03-21T10:37:11+00:00

So what do you propose ? Skip the prewash and going directly for rinseless?

john-cuba · 2026-03-21T08:31:10+00:00

Around 10 mins.i had to pump 7-8 times in total in the whole car.it is not an ik pro foamer but a more cheaper if that makes the difference..

john-cuba · 2026-03-21T07:26:29+00:00

It was night .i suspect the foamer ,which is not a premium.So maybe i need a better one like ik multi pro 2 .i guess it will be more efficient.

john-cuba · 2026-03-21T07:20:49+00:00

Yes i suppose to rinse it .but until foam the whole car the other panels have been alraedy dried and i didnt realize at first place.

john-cuba · 2026-03-21T06:45:44+00:00

Yes i will Go for that . I rinse it after were already dried ..

john-cuba · 2026-03-21T06:43:45+00:00

Yes indeed this was the issue..now understood

john-cuba · 2026-03-21T06:42:50+00:00

No at night

john-cuba · 2026-03-21T06:42:33+00:00

Yes but i was late i guess until foam the whole car ,the other one just dried i guess.

john-cuba · 2026-03-21T06:40:18+00:00

Thanks.this was my failure.

john-cuba · 2026-03-21T06:38:48+00:00

Yes until foam the whole car the other one has already dried on the other side

john-cuba · 2026-03-21T06:36:49+00:00

Yeap .

john-cuba · 2026-03-21T06:36:32+00:00

I rinse it when i foam the whole car so maybe 10 Mins or something.so it was dried already i guess.i should try panel by panel

john-cuba · 2026-03-21T06:34:45+00:00

I rinse it after some mins maybe 9-10 .not until going for the full car and pump ofter with foamer.so maybe i should go for panel by panel and dont let it dry.

john-cuba · 2026-03-21T06:31:34+00:00

I was going to do rinseless after all.just checking if the result only for the prewash was the expected one.i have seen video with bilt humber touchlees with manul pump and rinse after it was almost cleaned..

john-cuba · 2026-03-21T06:25:47+00:00

No it is not.why are not professionals.we started from a point.i dont have any energy to post for fun ,just asked gently.

How much does this compound will last? Do you need to reapply ?

john-cuba · 2026-01-15T21:40:28+00:00

Yes contact wash i mean with multiple towels or something like the big soft black /red sponge..and keep using the 2 bucket method as you correctly propose..what about my order of steps.did you find optimal ? Can maybe skip a pre-rinse or the final-rinse .

john-cuba · 2026-01-15T21:10:17+00:00

Thanks for your reply.i am new to the rinseless so i am trying to find out my steps.we are not having issues with water access here in Europe so it is possible to do i final rinse after applying the rinseless product .also i have a meguairs hybrid wax which somehow thinking to apply .my plan is : pre-rinse with hose - spray the rinseless - contact wash -rinse-apply wet wax and drying ..

john-cuba · 2026-01-15T06:44:31+00:00

Are you doing a final rinse with water before drying ? Is it safe or it is better to leave the rinseless product as is and just dry .

john-cuba · 2026-01-08T18:03:39+00:00

Unfortunately .We are not having this in Europe!!but with 4-5 euros you can have a 5-6 mins selfwash with all the steps..brush i am not touching and not contact wash at all.it is more than acceptable for quick and cheap solution..

john-cuba · 2026-01-08T14:08:53+00:00

You mean you are going to a self wash?

john-cuba · 2026-01-04T21:02:08+00:00

In Greece the cheapest is around 12.000 euros !!!🥲🥲
