At Sherwin Williams they sell a couple of products but about the only one that holds up is a two part acrylic that comes with cleaner and pigment and base. Cost about 70 a box ( gallon ) and a two car garage will take two gal to first coat. You can get over the whole thing with one the second time. Kinda has a vertical learning curve going down as it is thick but the key is hot tires or petro stuff doesn't bother the finished product.

Oh yes it is best to change the roller each gal on the 1st coat as it only has a 2 hr pot life and 1 1/2 is more like it. Bloody stuff starts setting up on the roller if you don't change out.
