Paint Stripping with a DA

I agree with the above posts......I would look at the air compressor, DA, changing paper more often. No way a deck lid should take that long with 80grit. Even if its painted with tractor industrial paint stuff.

Hitting the top layers with 36grit will go faster. When you get a hint of the primer or metal, stop and switch to the 80grit to get to the bare metal. 36grit leaves aggressive scratches in the metal.
