I didn't reply to your post at first since it sounded like you had made up your mind about U-Coat-It and since I used another product, I had nothing to add.....
However, now that Roger has opened the door and told you what he used, I'll now do the same.
After investigating a lot of different brands, mostly from reading threads on The Garage Journal
, I decided to use the Epoxy-Coat brand. I found that with the U-Coat-It brand, it was multiple coat process with the color coat first and then a highly recommended clear coat over the color.
Epoxy-Coat is a very thick one-coat epoxy that does not need a clear coat on top. In fact the manufacturer recommends not to use a clear top coat at all.
Just like Roger, I have documented my application here:
It's a "lessons learned" write-up documenting the whole process. After over two years of use, the floor still looks great. I do not "baby" this floor. I drag a floor jack around on it with no ill effects. The only time I cover up the floor when doing work is when welding. Then I put down a welding blanket just to make sure. The floor has lost a little of its shine where I do most of my work, but cleans up real well with some Simple Green. I've spilled gasoline, oil, and anti-freeze on the floor, and although I wipe it up as soon as I see it, I see no ill effects.
As 30modela stated, the biggest and most important part of the whole job is the prep work, regardless of which brand you use.
Hope this helps,
