On a 2000 GT (rag top if it makes a difference) is there suppose to be any kind of gasket or seal between the stock spoiler and the trunk lid?

I took the spoiler off yesterday, and was agast to see how much caked on dirt was there. When the dirt was removed, I was disappointed to see just how badly the deck lid finish had been affected.

I have evidence that the spoiler was not a factory paint job, and can see that the deck lid probably has been off the car. So, I wouldn't be surprised to know that a gasket or seal is missing.

Well, Ford says no. Factory supplied spoiler does not have a gasket or seal between it and the deck lid.

Now, what do I do about the excessive accumulation of dirt? Simply removing it should not be the correct answer. Don't think Ford envisioned removal of the spoiler twice a year. Besides, accidents can happen, even when we're careful

no gasket on my stocker either when I removed it; significant accumulation of crud around edge of mounting 'posts'. I put some duct tape on holes from inside trunk and then cleaned/clay-bared the trunk lid around holes - Cleaned up pretty well. When installing new 'boss' type spoiler I put very thin bead of silicone around outside of holes, installed new spoiler, put more silcone on studs where they came thru trunklid, then washer/nut. Also went back and waxed around mounting feet pretty heavily. Does seem a bit odd there was no gasket; easy enough to make one.
