I see that the GC50 is used before laying up the carbon on high gloss parts. But what do you use to apply it? I think the easy composites gelcoat spraying cup gun is a bit expensive, is there other ways to apply it and still get a high gloss result? Can for example a plastic spray bottle be used?

Hi!

IMHO, your best option is to try to locate a supplier of Epoxy resin that can be used for infusion.

check out marine/boat suppliers .. they may have usable things, even in Peru  :-)

I take it that there are also car paintshops?  They can probably provide you with the mirror gloss finish you want, by clear coating the finished CF part.

It will probably cost you less than trying to experiment your way to a less satisfying solution with in-mould coats before infusion .

Another thing is ... parts do not become a lot easier to do by being smaller .. they just make mistakes and errors cheaper 

I have made several small parts (Bike mudguards, windshields, numberplate holders e.t.c.) by using good quality "rattle-can" (spray-can) clearcoat ..
I had to experiment a bit to find a really good spray-can clearcoat, but it can be done for small parts ..  For big parts such as a bonnet, I would not even attempt a 2-k spray myself, on large surfaces, even though I have some experience doing motorbike tanks and fairing parts. I pay the pro's to do their job ..

Bah, where's the sense of adventure Dravis!?

Large parts are no more difficult to spray than small parts, in-fact in some cases a bonnet is much easier than a smaller more complex part. Of course, you wouldn't want to do it with a rattle can, you'd need a proper spray gun. But still... The only times I've ever run into trouble with my work is when I've got other people involved. I'm still paying for the last job I got a professional spray painter to do for me. Even highly reputed professionals cut corners sometimes. These days I do everything myself, to make sure it's done properly.
