86 GT 2.8. There is an inch of water in my trunk after a good rain. It does have a spoiler that I just reinstalled, and sealed real good with new rubber gaskets, and silicone. There is no evidence that rain is getting in from the 4 spoiler mount bolts...Are these cars noted for leaking down through the louvered battery, and air cleaner covers, and getting into the trunk somehow, or anything else? The rubber seal around the top of the trunk area is new...This is without driving it in the rain, so it's not coming in from underneath. No evidence of wet carpet where water might be running down the sides of the trunk, unless it's drying up before I discover the water in the bottom

Those spoiler mount studs can be really sneaky.

Yeah Gall, thats what I'm thinking. If it ever drys up around her (Buffalo) I'm gonna run a bead of silicone around the outside, and inside of the gaskets it's sitting on...Unless you have a better idea. I'd like to seal them from the outside though rather than the inside if water is getting in there I don't want rust happening...
All I did when I installed the spoiler was to put a glob of silicone on the bolt holes. Like I said though, this time I'll get em all around the gasket inside the lip, and around the outer perimeter......[This message has been edited by FX (edited 06-16-2019).]

Hard to believe that so much water can get in via 4 little holes, but it happened to me a few years ago.
I put clear silicone around the stud on the inside and tightened the nut to squish it into the hole.

That sounds easier than what I was planning. How'd that work out for you?

No more water in the trunk! Although my car is now a garage queen and the only water it sees is from the quarter car wash.

Sounds good, I'll try it your way Gall. Quarter car wash? where do you live, in 1960?

The GT has D-shaped plastic trunk corner pieces (D-plates) that square the ends of the rounded trunk opening to match the width of the deck lid, and provide support for the trunk seals.
They are not present on the notchies, as the deck lid is wider than the GT deck lid.
The D-plates are usually the source of a GT trunk leak.
