I bought some black seam sealer from Napa or B&B auto, it wasn;t 3M but thier generic brand for 1/2 the cost of the 3m stuff. Goes in a standard caulk gun, worked just great.
Eastwood makes a good seam sealer too, used their stuff when it came up on sale, its very nice to use, Eastwood stuff just seemed to spread & stick better, easier to control the bead your laying down, Bondo gets brittle,
Don't use bondo, it won;t expand & contract & will eventually just drop off!
