For the guy looking to use the U-coat it stuff, read everything on the subject at
www.garagejunkies.net, a lot of negatives about U-Coat It, especially warranty help (supposedly deny everything) If you want to use Rustoleum,use the solvent based' Industrial coating only comes in gray, but A LOT more durable than the water based Home Depot Rustoleum kits. You will have to buy it online. The results are all in the prep, vac floor, wash with detergent, let dry, acid etch (muriatic), scrub and rinse 3 times, let dry and do the finger test ( wipe your finger on prepped concrete) if nothing shows up, start painting!
