Just thinking out loud here... but would that really solve the problem of a resin that can't handle the heat? The part would still get hot and the part would distort? Or do you just suggest that to try an salvage the existing part?

Yeah I would think that would be more of a band aid fix more than a solution to the issue at hand.

I'm kind of confused as to why i feel the need to defend my post... but here goes.
The sanding and clear coat is a faster and less expensive way to make the current bracket look good/better. He said he used West Systems epoxy... should be plenty durable enough for an underhood bracket so long as its isolated by a spacer from the cylinder head and engine block. Yellowing is going to happen no matter what resin is used. All resin yellows, some faster than others.

Fastr, if the original part is failing due to the temps, adding a coat on top isn't going to help protect it. It will make it look nice for a bit, but it's still hot in the bay, and the entire part will soak in the heat, isolated or not. The only way to make it so the part stays perfect, is use a high-temp service resin...from the start.
