I have just undercoated the tire side of my painted inner fenders. I cleaned, degreased, cleaned and scuffed the surface before applying TiteSeal paintable undercoating. After about 3 good coats and following the instructions to wait until completely dry before painting, I am getting ready to top-coat. As in the title, I am using NasonFul-thane 2K SS Urethane (I think used to be Du-pont) to topcoat.
What I cannot find is whether to prime the undercoating first, use adhesion promoter as if you were to paint on plastic, or the undercoating acts like a primer and can be directly top coated. Any experience in this matter or working with 2K paints would be appreciated. I did search the safety data sheets and instructions for the undercoating, pretty vague.
I know there are a few people here with paint experience like @azblackhemi and likely others.
Thank you
Marty
