hello,
I have a 97 del sol. and since few years, I have gettign this wind sound on the driver side if I drive over 50mph. It has been bugging me for a while.
I took it to an auto body shop, and they told me that it would cost me 200 dollars (parts only) to fix it.

this isn't my del sol.
but as you see on the picture, the circled window strips are very loose. If i put force on it, I could move the inside weatherstrips around. I am thinking about fixing ti without replacing parts... If I could somehow fill up the little gap between the weather strip and the supporting triangle thingy (about .5mm) with some kind of glue, then I think it might work. the body shop person told me not to do it because it will cost more to replace it later if I screw up. I am thinking about getting an needle shot thingy and suck up some glue and inject glue into the gap. But the problem is that I Do not know what glue to use. I have the epoxy glue (the one that mix two solution) and some silicon from home depot.

Help me please!
