ok so here is what I am doing. I am replicating a cover for my subaru in carbon fiber. I wanted to start with something easy as I have a lot of experience with composites on aircraft but I have never done anything that required a quality finish such as this. here is a picture of the part in question


so to make the mold i was thinking orange tooling gelcoat and epoxy putty. my question is can the bond-o putty be used or is that not any good? If not where can I get putty here in the states? I am also hoping to cure the actual part under heat.
secondly what kind of problems will I be looking at with the recesses? when it comes to the layup? I would like to keep the pattern uniform. I’m thinking there will be some bridging which is obviously unacceptable on the surface. I am using 3 layers of 2x2 carbon twill with the west system resin doing a wet layup and vacuum bagging.
I am hoping to use the mold for several times so i can sell some of these to fund future projects.
thank you in advance!
