Hi there!

I need to build a CF part wich will go in a high temp environement (inside an engine bay)

as i need the part to have a nice glossy finish, can i use the epoxy clear gel coat before vacuum infusion?

And if so, is the gel coat need to full cure, or tacky when i build the reinforcement frame before start infusion?

Kind regards,

Seb.

Hi both Matt,

thanks for this replys.

the part i will try to produce is an engine cover. original is plastic, and there is no stress on it (just a cosmetic part).

i ordered high temp epoxy resin last time, so i think this part will infuse with this resin.

I think i will try 2 parts:

1 only High temp infusion, no clear gel coat.

If result is not good, then i will try clear epoxy gel coat.

Thanks for your help (here and by e-mail)

Regards,

Seb.
