E coat

I have never painted any new parts that what I guess is e-coated.( they are black). Can I simply skuff and base coat? My plan is to scuff and apply a coat or 2 of SPI 2k regular build primer. Then wet sand the 2k with 600 as it’s a metallic base coat and clear with universal clear. I am doing a fender and hood on a 2021 ford f-150 for my brother. The bottom of the hood looks like it would be a nightmare to prime and sand all the nooks and crannies. Thank for any thoughts.

OEM parts can be thoroughly scuffed with red pads, cleaned with #700, sealed, then painted. Never, ever go straight to base on top of e-coat, it will chip off. For aftermarket parts, you are on your own. The primer quality of those is highly variable and you have yo do some testing to see what might work.
 
Thanks for your response. This is the underside of the hood. It’s aluminum. So I need to skuff this and then prime and sand? If so that’s gonna be a tedious part to get sanded!

Thoroughly scuff sand, then SEAL, then go straight to paint according to the proper procedure. Priming it will make a lot of extra work, you can do that if you insist, but I wouldn't.

Also, the picture doesn't show, and you haven't said if the part is OEM (Ford).
 
Crashtech, thank you very much for the replies. I am learning a lot from the forum and I am confident in all my actual work. It’s just the different processes that I still struggle with. Ok the parts are not oem. When you say seal what SPI sealer should I use. Reduced 2k primer, reduced epoxy, or just spi sealer?

Great! Also the top of the hood could be skuffed with maroon pad and presto , then epoxy sealer, then basecoat?

Being it's a metallic it's safer to use a grey scotchbrite and scuff stuff. If you only have a maroon or can't get any grey, use a worn maroon if you have one. Scuff the underside and save that one to do the top with sanding paste. Don't dig in, or press down hard with the pad when doing the topside. Just use plenty of paste and let it do the work.
 
Chris, thanks. I do have the grey pads. For some reason I was thinking I had to block sand the top of the hood because I’m always working with beat up panels, but then realized it was new and dosent need to be blocked flat. So this is going to be much faster and easier than I first thought. Grey pad with paste, reduced epoxy, base and the next morning clear.
 
I always quickly run the ecoat over with a orbital with 400. If I see any imperfections I sand them out. I use a red scuff pad on the underside.
