We had a load of tar in our wheel wells from our 05 journey back from Texas. Last summer a car enthusiast friend stopped by while we were washing our casita
and recommended we use wd40 to take the tar off. It worked like a charm and took off all the gunk without much effort and without any abrasive scrubbing.
After we used it (so successfully), I was told it is not a good idea to use a petroleum product on fiberglass.
Anyone out there know if it is a good or bad idea to use WD 40?
Thanks in advance
