Profile Sanding Tip Using Auto Body Filler
When I have a lot of molding to sand, auto body filler can make a fast profile sanding block.
Profile sanding block
To make a fast profile, apply a mound of body filler to a scrap of 1/4" ply. Lay some thin plastic wrap over the filler and press a sample of the molding into it. Make sure the entire profile is filled, then leave it to harden.
Once the filler is hardened, remove the scrap part, and trim the block to size. Sandwich a piece of sandpaper between the block and the molding, and go to town.
Like the card trick I posted previously, rolling the sandpaper breaks down the backer and makes it more flexible. Bond the sandpaper to the block, and you can use it with a stroke-type detail sander, like the Porter-Cable.
