Discolored Propane tank door
I have a 2010 Montana Mountaineer and the propane tank access door has a discolored area of approximately 5" x 10" that is a tan/gold color. It appeared recently and I was wondering if anyone else has experienced this? I do not know what it is and have tried to wax it out but that does not help.By the way the RV is white gelcoated.
