Re: Whats up with these gas tank caps?
After several ruined paint jobs and the discovery of gas resistant clear coating I fixed my problem by adding another gasket. I made it from a heavy duty inner tube. I tried placing it behind the original to take up some space and get a better seal but discovered that it worked best by placing the additional gasket on top of the existing one. I haven't had any problems with venting.
