We buy JB Weld by the truck load and cram the empty spaces in the truck cab and drivers pockets with Gluvit. LOL
JB is usually used to to fill holes. Like when PO gets drill happy after buying a new one. :blue: Gunnels, metal decks and transoms are some of the most used places. It is good for filling and smoothing smaller pits.
I recommended the plate and 5200 because 5200 remains pliable like rubber after curing, And those look to be large pits and the pitted tin will be thin, so the 5200 cushions the plate and helps to back up the thinned metal. That part of the hull gets a lot of water pressure from wakes and just normal running, not to mention rocks and semi-submerged logs, so a fix should be as strong as it can be made.
Gluvit is a runny epoxy-like product that oozes into seams and around rivets, It has a drawback - It is brittle after curing and can crack if flexed. One more thing about - It is not UV resistant and sunlight will destroy it. If it is exposed to the sun it must be painted, It is good under a deck protected from the sun.
It isn't always easy to clean up before sealing, like in the V and all the crevices in these old tinnies. And naturally these hard to clean up places are where we find corrosion.
