Re: Whale spoiler gasket?
I have my spoiler off -- I'm doing some custom body and paint.
To answer your question; yes - there is a small o-ring around each of the bolts that protrude into the hatch. You can get these at any decent hardware store.
Mine had a small amount of rust (very minor) on the bottom of the mouting base of the spoiler. But we don't get much rain here in So Cal and my SRT6 is always garaged.
I can take picture tonight when I get home from work if you would like.
