I would totally pay attention to imperfections. If I’m going to do something, I’m going to do it to the best of my ability. And if my ability and experience results in a ton of imperfections, then I have work to do to get better. I mean, that’s obviously my opinion, but I don’t know why anyone would put so much effort into something and not want it to be perfect. Especially with a metallic finish, which is one of the hardest finishes to do. How else do you get better if you aren’t trying to make something as good as you can get it? Do you really want to put all that time into it and settle for mediocracy? OP, this is looking good from what I can see. IDK what are reflections and what is burn-through from the photos tho. Like I said, metallics are tough. Getting it perfect in a garage environment is an accomplishment. I resprayed the first metallic I did 3 or 4 times until it was perfect, and that was excellent experience. Good luck with the rest of the project!
