Seam sealer

[kb426]

I'm going to have several seams to seal. Does anyone have a product that they recommend?

I usually use 3M fast and firm.  Some urethane reducers can be used to shape it and clean it up some before it starts to set up.  I have always felt that there is a better product somewhere but I have not found it yet.

Last car I painted was in 2010 but I used 3M 8308 outside the weatherstrips and 3M 8374 inside them and underneath. Both can be tooled with solvent for a short time. Anything 3M that says urethane on it is a safe bet in my opinion. I have found 8505 to be too fast and too firm for me. Heres what I mean by inside and outside the weatherstrips. The black stuff is 2K and can be sanded for shape when dry.
