Interior paint

6B929A29-FD24-4F64-9771-9AA4C9062069.jpeg This is the blue paint I’m going to use for the 69 Valiant interior in conjunction with the Bulldog Adhesion Promoter.
I was told by the guy at Mr. Moparts that you want to use an adhesion promoter like the SEM Vinyl Prep or Bulldog before spraying the color.
Eventually I should have a good comparison between the SEM products that my buddy told me about and the Bulldog/ Mopaint products that Mr. Moparts sold me.
