I’m looking for a good paint I can put in a spray gun and sticks to polypropylene well. I’ve got a good number of those street signs made out of corrugated polypropylene and I’d like to cover with white and remake into new signs. I’ve been told the best cleaning treatment for this plastic would be to clean with 50/50 alcohol/water, sand with 80-100 grit, then wipe off again with the alcohol mixture. I’m open to more advice here if you have some.
Anyone aware of a paint sold by the gallon that sticks to polypropylene well? The cheaper the better of course.
Good question, not aware of what would be the best. I use Sherwin William for most of my stuff, I am sure they will know. However, while their stuff is good, it’s not cheap.
