Started this project for a friend a couple months ago and will be picking it up again in April/May when temps get warmer. This was his dads old surfboard left in the woods for years, then in a shed for last 4-5. Has sentimental value even though it will be completely different other than original foam when done. Believe it is a 7'3. Found some images of similar boards in better shape online, with slight differences in the butterfly locations and sizes.
It weighed 26 pounds when I first got it from him. Might have been more before being moved into a shed for 4 years. After removing old glass from board except for rails, removing loose guidance system fin box, and letting air dry for a month, weight last check was about 15 pounds. I'd love to see it get to 14 or less before reglassing next year.
I plan to fill in some holes/low spots in foam with some total boat foam mix in the spring. Im curious if I should dig out some of the discolored foam areas or just let it be after a winter of drying (maybe some warm sunny days outside in April/May too). Same for the old fin box void. I assume I should just fill it entirely with new foam then cut out new space for modern fin box?
if you look closely you can see where vegetation was growing out of stringer at the tail like a mini tree. There was a delamination on the deck the size of your torso. Foam was in best shape underneath that area in terms of no water damage. Elsewhere the board had been soaking in it.
any random thoughts/oberservations welcome. Letting it dry further for the winter before continuing work on it in warmer months. Plan to seal with two 4 oz fiberglass layers after repairing/leveling foam, hot coat, and then paint with 1 part polyurethane wet edge paint.
