  1. Motorhome - Oxidation Build Up

    Automotive Repairs
    I just bought a used motorhome (1985 Ford Elderado) which has a lot of oxidation build up on the exterior - does anyone know how to remove it? or a compound that will remove it? I believe the exterior is fiberglass. I don't know if just a buffer would work or if I need something as an abrasive?
  2. Ditra:can I make up 3/16" difference between old & new floors w/ thinset under Ditra?

    Flooring
    Ditra:can I make up 3/16" difference between old & new floors w/ thinset under Ditra? Have 3/16" difference between small area of old subfloor (lower) and new subfloor. Home Depot guy (I know ... that's why I'm checking) says it should be ok - but use 3/8" notched where I'm trying to build up...
