I got mine installed this weekend. I'll post some pictures. I used the 3M marine adhesive. I marked the outside of the mounting pads with tape. Then sanded with 220 grit sandpaper. Took the tape off, cleaned and dried it. I then made an outline with the caulking and put more caulking on the inside. Placed the mounting pad on top. Put the bolts through and before I pushed them down, put a nice bead of caulking and spun the bolt around as I pushed it down. This gave the bolt a nice seat of caulking and when tightened, it pushed all the caulking out nicely. I left it on there since it's pretty thick. All in all, it was a fairly straight forward installation.
