I'm not sure how common this is but it affects both my 2001 SL2 and my wife's 1999 SC1. If we wash the car in winter the gas door won't open. We have to have one of us pulling up on the release lever while the other pries open the door with a key, etc. to open it. When it warms up everything works fine. Is there any way to prevent this? I've heard of some people using a silicone spray. Where do I get this? Cheers!
