Bow deck

Hi Folks

I need some advice. I just got a brandy stainking new Duranautic 13 ft. aluminum v-hull (pointy kind) and it does not have a bow deck for my future trolling motor. My first thought is to drill into the top of the aluminum rub rail and put flanged threaded inserts into the holes. I could then bolt down a fiber glass/wood core pretty painted bow deck. (with a battery shelf underneath. It isnt going to be for standing on just for the tm. However if I ever need to get out of the boat through the front it should be able to take a temporary step. It will only be about 2 feet long. My question is.....I dont want my inserts to start turning when I tighten down the deck. Would JB Weld be enough to hold them down? .....or some other epoxy/adhesive?

Thanks

Sonny
