## Questions & Answers

**Q: would these work to remove paint off a concrete floor?**
A: Yes, but if you have a large area to do the discs will get gunked up with paint.  Might want to use paint remover and a metal scraper.

**Q: Are these good for wood?**
A: They are actually VERY good on wood. Much faster than most sanders. You have to have a steady hand though.

**Q: can this be used for sanding a jon boat?**
A: I wouldn't recommend this for sanding a Jon boat as too much pressure with a grinder could penetrate the skin of the boat.

**Q: what grit on these discs would be best to remove light rust and smooth paint on body of a  10 wheel dump truck**
A: I would think 80 grit would do best for the light work you’re describing.
