The top laps I carry are rigid, facet rated laps. For years I only carried non-PSA because facetors wanted those. The Ameritool and High Tech units run much faster but the non PSA work fine if placed on an existing lap. If they slip put a little water on the lap under the top lap. I had so many people asking for PSA backed I transitioned over to them after giving up shows where I sold to a lot of facetors. Everyone complained that the non-PSA worked fine and cost less so why don't I have those? Now I carry both. I stock a few Hi Tech brand sanding discs but don't have them on the website. If you are doing domes the foam discs work well under the sanding discs. For flat work you will have better luck without. Another polish method is to use the spin on 5 1/2" or 6" polish heads. They have same screw size as the bolt that hold down the laps but full face surface.
