I did the rustoleum kit from lowes. Overall, pretty easy to use. Did it all in a day, just hammered it out.
I will say that his looks better than mine. But then again I was rushed and didn't spread the fleck-stuff out very well. Also I now think of how mine looks...4 years later.
Overall, on the rustoleum kit, first off, buy the kit a few days before you do the work. READ the instructions...then go back and buy all the crap you then need
. Then follow the instructions and go. Pretty easy. I let mine sit for a week after I painted it. This was back before I moved in and I had to be out of town for a week, so I knocked it all out and let it dry. Just a month ago, I found a small spot...less than the side of a dime, where the paint had come up. This is years after parking on it everyday. Or working on the floor, etc.
Typically I don't drag my jack sideways on it. Also same with jack stands. For stands, I put a piece of wood down under them.
Usually after a large project or something, I'll sweep then mop it. Makes it look nearly new again.
