Successfuly made some pre preg. Wanting to clear coat. Untill I get set up I'm using rattle can acrylic.

I key in with 800 grit but it drys showing all the 800 scratches .

Would this still happen with proper mixed 2k clear coat?

Thanks

Depends if you use a high solids clear or a medium solids clear. For medium solids you want to prep with a gold scuffing pad rather than sand paper. For high solids, you can prep with 600 grit.

What's the difference? Mainly spraying small parts of that makes a difference

Like name suggests there is higher solids (HS) content. It is also called scratch resistant clear... i use ultra high solids (UHS) clear to coat CF and can even get away with 400 grit but most of the time i finish at 800. All offcourse 2k.

Nice thanks. Can you also point me in the right direction for compressor and spray gun. Also what brand of clear coat do you use. Is it acrylic 2k?

Its PU UHS clear....... its our local manufacturer but i am sure you can get it near you in specialized store for car paints & bodyshop equipment. 

Ask for advice on spray gun and compressor there as well. I dont know exactly wgat brand of gun i am using (one small and one big) but can make pics if needed on mondaySmile

If you're looking for a proper gun, then the DeVilbiss GPi is an outstanding all-rounder and lays down a bangin coat of clear. Or if you are on a tighter budget than that, then the DeVilbiss SGK-600 (also known as the FLG-5) can handle primers and base/clear coats quite well; while the A.N.I F160 is very good for it's price at spraying basecoats and clears (you could spray a primer through it, but it would need to be thinned down a lot).

Personally, I use the SGK-600 as my primer and base coat gun, and the GPi as my clear coat gun.

Buy any of those from Spray Guns Direct and you'll be set.
