Yes you can. I don't have a angle grinder thats why I went with the sander and worked good I did that in 2 hr. Now as far as the polish I have a old car buffer I am going to use for that. Just have to find the compound. All home depot had was a little stick of it.
So this was my first attempt at a all grain. Has a really bad smell kinda burns your noise... Should i just dump it and clean everything really good? ????
