i had a good chat with them at the bike show this weekend (they were more or less the only interesting thing at the show...)
Their products are all matt, but then can be reworked to a gloss as needed with sanding and clear coat. Its worth having a chat to them, but the jist of it is that depending on the colour used, you may have some sanding to do for a proper gloss finish, and they sell various clear coat products to achieve the desired finish. the paint itself is pretty rad, goes on thick, doesn't run, dries quick, only needs one coat. after that you can do a matt/satin/gloss clear coat for extra protection, and some of the clears come with fancy sparkly stuff in it too if that's your thing.
I'm going to be using their stuff on the old Tracer rebuild i've been meaning to get cracking on, either pink/fluro green or purple/fluro green. apparently their stuff works well for a hydro dip finish too, i'm still pretty keen to give this a whizz despite early failures with supercheap auto paints.
