Not knowing the panel manufacturer I would suggest a test wipe with some lacquer thinner on a rag, just damp the rag and quickly wipe across the panel then go behind it with a dry rag to see if the black comes off onto the rag. Some places used to use a cheap black primer instead of the EDP to save money. I dont think anyone does that any more. scuff the fender i use 220 grit to sand it down then I put two or three coats of[ I use Omni] MP282 high build primer. Now the core support and inner fender you could do the same depending on the level your trying to make your truck reach Normally scuffing those parts wit a green or red scotchbrite then coating with your desired top coat. I lot of people use the Blitz black to paint the under hood parts and if you have a John Deere store near you you can swing in and get that it spray cans or quarts or gallons as well. Just a tidbit for free that Blitz Black also is super vlose to the color of the tilt columns. Jim
