borrowed a friends creeper and just spent a good hour under there. Been about 5 different sealants applied to fix this issue.
Previous post i asked about the inside hull chines and keel about being seamed above the chine/keel/ I took y screwdriver to the weep holes and feels the hull is stamped and only joint is the outside chine to the sides of the boat?
found a couple more missing rivet heads but no flex in them, i will blind rivet anyway
the hull at transom appears to have had the boat launch onto the ramp a couple three times. One non flexing missing head and about 20 chewed up heads. I'm prob going to flexseal that to see what happens as well as sika caulk up the outside chines. I've got them brushed clean. I think i'll do the siki first, run and see if any positive results before I flex seal. I kinda want to know where prior to pulling the floor sometime in the future. Headed for another surgery in Dec so floor project is not happening soon.
