Im spraying a bumper using waterbased basecoat and going to finish off with 2k clear over it.
I sprayed my base coat 3 days ago and didn't spray the clear on it as i got a few runs and bit of crap in the base coat i needed to sort out first.
So after sanding out the runs my plan is to spray the entire bumper again.
so my question is can i just spray base coat on the entire bumper that i sprayed few days ago or do i have to rough it all up with 800grit first in order to get new base to stick to the old one?
I know lacquer needs to be sprayed straight away after base coat is applied but what about basecoat on basecoat after 3 days? Will it stick or do you have to sand it to make it stick.
Thanks
