Yea it is durock I wish I knew how much of a pain it was to cut and fit before I started. I think that's been the hardest part of the stand....until I realized they make a special blade for cutting it, went through 6 blades in 1 hour. The buffing I haven't done before but plan on using 400, 800, 1000, then 1500 grit sandpaper but haven't decided on a compound just yet. I should be able to go to an autobody store and pick something up..will probably do that on the way home from work tomorrow.
