My car has a lot of trouble starting after it has been parked in the rain. It eventually starts and idles rough then chugs until I guess the moisture is dissipated. I am assuming that moisture is getting into the distributer. When I do my tune-up, i plan to seal the distributer with high temp silicon sealant and prepare the inside with wire-dry and/or wd40. Could any of the things I plan to do to the distributer cause other problems?? thanks, Adam
