Not sure where you are with seam sealer, but I thought I'd mention I had a decent experience using these two products. Some of the reviews say that the viscosity of the Eastwood product is a little thin, but I used it on a 55 degree day, which probably helped alot.
I used the 3M down inside of larger gaps, then 2K over the top. Pretty hard to go wrong with 3M stuff.
Also, awesome work over the windshield, that's a tough area.
