I bought an aftermarket hood that has the cowl induction and has a billet insert on the front. My question is: the part where the billet is located is plastic, and is going to be painted the same color as the hood. I was going to spray it first with the Bulldog plastic adhesion promoter. Do I need to spray sealer on it after I spray the promoter? I am going to attached it to the hood before I paint it because it needs to be glued on and I don't want to run the risk of getting any glue on the fresh paint by mistake. So spraying it with sealer may not be avoidable since I am going to seal the hood anyway. And another question: will it hurt the primer on the hood if I get the promoter on it?
