I'm hoping someone has had this happen and there's a happy ending. Western Washington has been experiencing some unseasonably warm weather these past couple of weeks so I took full advantage this past Tuesday and decided to go for a ride around the lake. Much to my dismay I noticed brown residue on my sidepipes and my car cover burnt. Apparently I put the cover on too soon on my last venture. I've tried acetone and it took alot of it off but any self discerning critic will notice the residue which remains.
Any Suggestions?
