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?

Plastic spray bottle? 

Hello,

What country are you in? Can you get Scott Bader Crystic Glosscoat or Duratec Sunshield where you are?

You can spray infusion resin as a coating, however there are a number of issues with it. The biggest is probably that infusion resin is not thixotropic at all, which means it will run and sag extremely easily on any inverted surfaces, and will want to pool in the lowest areas. Also, with most epoxies being a 100% solids resin, it doesn't 'flash off' at all, meaning you can't really spray coats and allow them to set-up before spraying the next coat. Another potential issue, is that most epoxies do not polish well at all. This is fine if you can pull the part straight from the mould and be happy with the finish, but if you need to do any sort of polishing to obtain a high gloss finish then you're in for a bad time.

Hello Hanaldo,

Unfortunately when you can't get hold of things then you may need to stick to more traditional methods using materials you can get hold of. 

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 ..

Do not adjust our mind, theres a fault in reality :-)

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.
