Hi

I need to skin a motorcycle fender with cf, but it is in raw metal.

Do i have to aplly some primer first, to prevent the appearence of rust?

Pedro

Hi Pedro,

No, you should be fine to apply the skin of carbon fibre direct to the metal; in fact the epoxy should act as a primer, ensuring that water cannot reach it. Ensure that there are no areas that are not covered by the resin otherwise these may be a point where corrosion could start but providing the metalwork is completely covered in the epoxy (used for the carbon skin) you should be fine.

Best regards, Matt

Hi Marc,

The bond would be better to bare, keyed, metal than it would to the plastic of the paint. Likewise, I would say that the bond of the epoxy to the metal would also be better than the bond of the paint to the metal too so if you have a choice then bare metal is the way to go.
