May be a bit of a weird question but:
Can automotive paint, not 2 pack (ppg) be applied using a brush? I'm going to be doing some art on the bootlid, and will be using a brush for some bits. I don't mind if all the paint isn't perfectly smooth but I will try to keep it as thin as possible, then will flat it out and probably laquer the entire thing.
Like I'm said, I'm looking for an answer whether it will stay on the car or flake off etc, rather than whether it will give a perfect finish
Cheers
Yes, celly can be applied with a brush. Thinned 1:1 and applied in THIN coats you will need 30 coats, yes 30 coats over a visible substrate, flash off time is at least 15min between coats so you're looking at well over a day painting. All substrates must be perfectly flat...i mean mirror FLAT I can't over stress this point so don't start your 30 coats until you're 110% happy you are starting on a mirror surface. Leave at least 24hours to dry, then cloursand using a sanding backing pad and 2000 grit wet or dry paper to take out the brush marks and other nibs. Buff to a high gloss shine with rubbing compound then some T-Cut and a good quality wax to seal off.
Cellulose paint is extremely durable so provided you've prepared your surfaces correctly and are willing to aftercare your paint in the months to come then no, it shouldn't flake off and you'll have a decent finish that I've seen outlive most cars I've painted with cellulose.
If you are new to this, I would always advise to start by practicing on an old scrap piece of sheet steel before you attack your pride and joy with the brush! Certainly until you're confident at using the products and have mastered the techniques needed. Brush painting with celly is pretty difficult to master and requires a lot of patience to get it right so be prepared for a lot of trial and error if this is your first time. And I'm not sure if this method would work with the artwork you have mentioned anyway?? so yes definately, practice on something OFF the car to start with!!
Good luck with the project anyway.
