Like many people on this site, I want the biggest bang for the buck. With that said, when I choose materials or tools, I never buy the best or the cheapest, I attempt to get the best price while meeting my level of quality I need. My requirements are in order of importance:
-Fitting my budget, in this case $800-$1000, not counting supplies and labor
-Something that will last, I'm not going to redo the floor in 5 yrs. from now
-Looks good.
So from reading specs and lots of posts on this site, I'm putting down SW Armorseal 1000. It's an industrial product, has good reviews, and I can afford it. I don't plan on putting down a primer, just 2 coats of the epoxy. I was considering the flakes, but with the clear coat, it drives the cost too far up. And really for what I'm doing, I plan on restoring cars in the garage, the flakes are really just for looks. I won't have cars coming in and out of the garage, so water isn't and issue. Hopefully it won't be too slick.
