I used Racedeck - IMO don't. The stuff is sort of hollow so tools bounce. Grease gets into the white tiles and cleaning is tough. Worse jackstands sink into it and so do jacks. It's slick when wet and tires can spin if trying to push up over a lip or something. If I do it again in another garage it will be epoxy all the way!

 

Titles get scratched and jack wheels stress them. I wouldnt do the tiles again esp not with a marble smooth floor.

 

Yah, I think a mechanical etching followed by a high quality 2 part epoxy with traction aid is the way to go. The traction aid will make cleanup harder I think but wet epoxy is about as slick as snot so IMO it's needed!
