Thread: Wet sanding?

I use both water and oil on wet dry paper. I think that oil works better but I do not like the mess involved. A drop of dishwahing soap in a cup of water is a close second to oil.

Odorless mineral spirits, kerosene or oil all work well with most sandpapers that are designed to be used dry. The gold type papers (Mirka gold, 3M’s 216u) are available in low grits and work great on metal when used with a non water lubricant. (water ruins the glue holding the abrasive and the paper backing)

Sanding belts are available with the latest and greatest abrasives and are easy to order. A cut up belt will provide lots of paper for hand sanding. It is a good way to get lower grit and higher grit abrasives with quality abrasive.

I do not use water, now. I use oil only with #2000, my last step before polishing cream compounds (for cars). I use sweet almond oil, just because I have it at home. It works well preventing rust (with water at #2000 after 30 mins I could see little yellow points appearing on the blade). After #2000+oil, I handsand with #2000+solid_soad, starting handsanding the soap (..not 30 mins! just few secs!!). This helps me to finish the work, since I can not find anything "smoother" thank #2000.
