I wanted to make sure the matte would not be affected by moisture in the future. So I cleaned the cowl, used POR-15's metal prep, and then coated the surface with POR-15. After it dried for a couple of days i began laying the matte. I knoe POR-15 has mixed results. I have had varying levels of adhesion myself however, on spots that I was careful in prepping it has very good adhesion, especially on light suface rust that was prepped right. The underside of the cowl had a slight dusting of rust so I am confident it will stick well. The POR-15 does not seem to do as well on sheet metal that has nor corrosion. I take it you guys think I may have "screwed the pooch?"
Thanks for the input...
