When I asked a guy in the NAPA store what to buy to remove scuffs from various panels - especially in cargo area and lower parts of doors - he told me to try baby oil. I did and it worked on all but the really heavy scuff marks.
Never heard of baby oil for scuffs. Meg's #40 does an awesome job I know that. When I get kids and can't afford Meg's anymore I may have to try this one.
