dried sandwich spread sealer?

I don't remember now exactly what I used. It was a putty type caulk (non hardening) that was in a tube that I could put in my caulking gun. I ran a nice heavy bead and then installed the fenders.

I never thought of it when I did it, but I bet you could use putty tape like used for mobile homes, RV's etc. Dang it, why didn't I think of it then, lol. :banghead:

You might find it at a home supply place or an RV center around you.
