Interesting dilemma - when I wet sanded the fuse, the 3M fine grit 220 paper gum's up badly, when I dry sand, the same 220 grit paper barely collects a speck, as shown. The photo shows the shiny un-sanded side vs the sanded side. The 220 paper cuts evenly. The high and low spots clearly show and level out after the sanding. I am pleased with dry sanding the Avenger. I will move on. Chic
