Working on the rental house today, I sat in a patch of white fiberglass repair glop (unknowingly) and then went out to move my car and smeared it all over the seat. However, I had just bought a spray bottle of "KRUD" remover...and it worked marvelously.
AND about an hour after putting the rental sign in the yard, I got two calls of inquiry...will show it for the first time tomorrow.
Pretty lucky I would say. Happy St. Patrick's Day!
