So here goes, with those compounds you are generally looking to create a mirror finish, you know those kits that are stupidly glossy? Well tha\is is the stuff they are using with a combination of gloss coats and wet sanding, its a long process and can bore the crap out of you if you aren't a patient person
Basically its gloss coat, wet sand, coarse compound, wet sand, fine, wet sand, finish.
You do that for each part you want stupidly shiney
I played with them when i first got them but havent applied it to any kits yet
