    Does anyone know what a "PU PSA" backing is for?

    I think its for peel and stick sanding disks - is this correct? (http://buycarsstuff.com/product/astr...a-backing-pad/)

    It looks to b a regular backing plate for both foam pads for detailing and sanding.

      I'd say PU is the material it's made from (Polyurethane).

      I'm pretty sure PSA refers to adhesive backed discs (or 'peel and stick') as opposed to hook and loop. Don't know why they're referred to as PSA and not PAS (peel and stick).

The silver one demands nothing and it looks just fine. I think the black vehicle is taking advantage of me, and the silver car is more my style. We can go out for a drive without her makeup and she looks fine. If I want to take the black one out, it is three or four hours in the "bathroom" to get ready.

          Pressure Sensitive Adhesive

          Industry jargon for peel-and-stick.
