I took on building a dinghy with my grandson and today we finished the rough work and tossed her in the lake to see where she might leak. It wasn't horrible but there are a number of seams that just aren't too snug so we're looking for options.

Fiberglass resin and just brush a few layers on over the seams, marine epoxy, fiberglass matting with expoy resin?

Will any or all of these work? Kiss is preferred and we don't really want to do the whole bottom in FBG
