After performing a resin infusion on my carbon engine cover am I left with a few holes in the surface. Is there a repair process to fill these in ? My thoughts are that I could mix some epoxy and hardener and simply fill in the holes and then sand/polish afterwards.
just wanted to check if there is anything special tips/tricks that could help.
Regards,
Lee

Hi Lee
Your talking about pin holes they are the curse of all composite work. I deal with them all the time.
This what I do.
1. lightly sand the whole surface and all the pinholes will show.
2.Wipe down with acetone or alcohol.
3. You must key or abrase each pin whole right to its bottom or things won't stick. I fold fine sand paper into a point and then twist when in the hole. Or a pointed dremel rubber abrasive bit.
4. If its tiny I will mix up some 2part automotive clear coat and dab and work in the clear with an automotive touch up brush that looks like a toothpick with a tiny brush on the end. (ask automotive paint shop they will have them) Make sure you are proud of the surface.
5. Once completely cured wet sand flat.
6 If you have fixed them all, clear coat the whole part and you would never know you even had pin holes.

Both the techniques above will work fine. Whatever you do, the key is to make sure no dirt remains...
