I've worked with his stuff before and it is really amazing
They do recommend some prep for garages, but the stuff seems to stick to anything...if Eric says it'll stick to your project, it will
He's a man of his word and the products seem to out perform any claims made
(refreshing these days)
I don't know if he can sell you direct for a DIY project, but maybe he can tell you where to get it...or something good available in your area
He does know his stuff so he's always interesting to talk/e-mail to
