New hood w/e-coat, scuff and primer?

[Nirky]

Got a factory replacement hood w/e-coat, was planning to scuff with red pad and then spray high build primer, couldn't think of any reason to first epoxy it beforehand. It this correct?

The E-coat has excellent adhesion and sealing properties. You should be fine scuffing and highbuilding.

The correct way to do that is to DA sand the hood with 220/240 grit on a 6" DA the spray one or two medium coats of epoxy primer. You can spray 2-K on the properly scuffed e-coat ---- but why would you want to ? (its a brand new hood). How a pro shop would do it is the way I outlined. Scuff, epoxy, then shoot your color coat then clear coat.

Thanks for the replies.

The reason I would scuff and spray primer is that the e-coat for all intensive purposes can act like epoxy would...bonds to the metal substrate like epoxy does (but probably better). It's not going anywhere.

Thus, I would be inclined to spray high build primer over that and block it to ensure everything's perfectly flat, who knows if the hood was mishandled or has slight nicks or even factory imperfection.

Do I have the wrong outlook here?

Nirky,

If the hood is in good condition then Phil is right just D.A. it with some 220 grit and epoxy then paint.

Most aftermarket hoods I have done usually have some dings or manufacturing imperfections that need some bodywork to be right so I usually D.A. then do bodywork then 2k urethane then maybe a sealer then paint..............:)
