Getting ready to seal air leaks into front cabin above front wheels and sides of firewall. I have some latex based insulating foam sealant that is minimally expanding made by DAP. In reading some old posts some have used expanding urethane foam insulation. What have others used and recommend.
I always thought that I would de-chipmunkize the sides first before resealing but I think that was a pipe dream and now I just need to get er done.

I used "Through the Roof" quart can of clear flashing sealant. Applied with 1" paint brush which I then discarded.

You can also use the "Through the Roof" sealant as a grab surface before filling the space with the crack-filling foam(if the space is large enough that the sealant will just drip through).
Even after cleaning the body panel with lacquer thinner on a rag-covered screwdriver, when I shot the crack-foam in there it did not take to the body material like I thought it would, and had to be manipulated into proper shape and brushed onto the body at the edges of the foam.

3M 08115,used it on both sides of mine, later I used a sledge hammer to straighten out the alu frame next to the place that was glued, no problem at all, a very strong product
Just do it right the first time, sealing it with foam or what ever is temporary at best

Actually you just need to remove the inner side panel, then clean the gap and sand it with 80 grit or so sand paper. park next to a wall or anything that will be solid, use a small amount of 3M 08115 in the gap and set pressure to the outside of the panel some lengths og 2 x 2 or 2 x 4 and a jack, leave the panel under pressure for 24 hours or so for the glue to cure and you are done
