With the PSA papers that stick to the back
up pad the paper always vibrates just as much and the sander with never any
slippage at all. Basically the paper works harder and lasts longer because
the back of the paper no longer wears out before the business side of the
paper. Still not convinced, I decided to test the concept. I worked for a
3M distributor and had access to all the PSA and non stick paper that I
wanted at no cost to me. I could make a full sheet of traditional paper
last for a couple of hours. I could make 6 applications of PSA paper last
about 1.5 hours. While the PSA paper did not last as long time wise, it did
do two to three times as much work in that hour and a half. Since leaving
the automotive business 8 years ago, I continue to purchase only PSA paper.
My time is much more valuable than a sheet of sand paper.


I wish I could find nice strong PSA paper. I have to use cloth backed to keep it
from ripping but the cloth backed does not cut as fast.
I have found so far as long as a sheet lasts for a plane that's enough.
