The trunk seal is only a couple of years old and looks brand new. It also appears to be on correctly. Where did I go wrong? Is there a method to follow to ensure it seals right or is it trial and error? Also the trunk seal & trunk were removed two years ago when I did my restoration during the painting process. Trunk is very very very slightly off, maybe a 1/32". But the fumes have always been there for at least 6 yrs. I will look into this problem tomorrow.
