Oh yeah, sorry I didn't quite answer your oirginal question, did I?!
Yeah, I generally paint everything I possibly can in flat, then I use the future. Some colors don't look all that shiny (like I would like anyway) and I usually just put on some Acrylic Gloss if that's the case, like I said the future will help protect the original paint. But it seems to be 50/50 with just putting future on by itself (without a second "gloss coat") but I really like painting flat, 'cause it helps ease the pressure of getting that perfect "wet coat" with gloss colors.....ever get a cat hair in your final coat??!! Drives ya insane!!!
