Greg & Jim & List I've been able to buff soft plastic by using the compound for buffing poly finishes, and by modifying my buffing wheel. I cut the top 2-3 layers of stitching and remove the threads, turn on the buffer and rake the wheel with a wire brush followed by a wooden paddle to remove any captured wire (can that leave a nasty pattern of scratches). The wheel will flare more and carry more compound. Be sure to load it with enough compound. It does the cutting/polishing. The wheel carries the medium and can provide the heat for burnishing. Clean the wheel often with the wire brush and wooden paddle. I learned this trick from a Kimball tech when the they took on Bosendorfers. Paul Chick RPT Plainview MN
