Hi Ben:

Correct technique for frame block dent removal is to grease the inside of the blocks and grease the frame; place the blocks around the frame and place the blocks in a bench vise; add slight pressure; rotate the frame back and forth a couple of times; increase pressure; repeat; repeat; repeat; until the blocks are secured firmly against each other in the vise. This pushes down the high points around the dent and theoretically pops up the low point, but it never does it completely; and it is obvious that there is extensive "collateral damage" to the paint in the affected area. Now you can clean the area and apply Bondo or other dent filler material and sand smooth. Don't bother trying this if you don't want to ruin your paint; it will. Live with the knowledge of the dents, and plan for your next repaint.
