sealing shower walls to pan

[gregg]

I found dampness in the cabinet forward of the shower. Upon inspection I found the caulk at the pan/wall seam had failed. This AM I started scraping the old silicon. I sprayed the walls with CLR and it leaves a clean-residue free surface on both the ABS pan and the phenolic laminate walls. I removed the rivets and spread the joint so I can get caulk down into the gap before installing the new rivets.
My question is-What shall I use to reseal this joint?

I have redone my shower with ivory silcone. It works well in this application and is what the factory used.

Maybe it's living on the coast, or working on boats, but we always end up using marine grade silicone, which is mildew and UV resistant. 3M 101, or if you never, ever plan on doing this ever again, 5200. However, 5200 is very permanent and it's a booger to get out, and that's where 4200 comes in, a less permanent version of 5200. Both come in fast cure, and both are 3M products.

Thank you for the silicone tip. We are about to redo our shower. We have noticed that the walls are not sealed to the shower pan. Surely this causes water to drip between! Is this a problem or is there some sort of seal between the pan and wall that you can't see from the outside?
