I always put old floor mats on the ski deck of my boat then put on 2x4's etc to support the cover
during the pa winters.
I pulled the cover and there is a stain in the form of one of the floor mats!
It looks like rust but there must have been a chemical reaction or god knows what.
It was NOT wet under there and rubber doesn't rust. I've been doing it this way since 1977 and this is
the first time anything like this has happend. I'll never use a tan floor mat again!
Does anyone know of anything to remove it or am I doomed to have it redone.
