Greetings, a friend of mine does the epoxy flooring on large scale, and when he has leftover (unmixed) supplies, I grab some. The durability is incredible, and he says the best result comes from trowing it, but you can brush as a last resort. Temperature is important (nice and mild is best). I'll have to find out the name of the stuff he uses, the cans simply state color and part a part b. I've used the stuff on my rowboat as well as floors, and is very versatile. Even with it's quality, I'm sure that repeated jacks and stand wear will occur. Touch up with brush.

As for your second question; vinyl. I'm planning my new garage layout, and told him I want a flame job for the finished car bay. His reply was simply, vinyl sign material, then apply clear epoxy. I guess that would work for checkerboard as well. Best of luck, and I look forward to seeing other opinions.

BTW, the stuff he uses is $185 for 1 gallon part a, and quart of b. Not sure if it will be cost effective for you. I'll get the name.
