www.musclegloss.com. I'm interested in seeing who's done this also.
GS400, have you looked at Rustoleum Epoxy? Not the stuff you buy at Home Depot, but the Industrial version--there's one place online that I know that will sell it to non-contractors. It doesn't come with flecks and only comes in one color, but it's supposed to be really good stuff. Check out
www.garagejunkies.net for a review.
Edit: Rustoleum Industrial DOES come with flecks, but the epoxy only comes in gray--I just ordered it. I also ordered some pigment from delviesplastics.com to hopefully turn the gray epoxy into a pearl white color.
