you havent messaged me yet i dont think. we can weld those holes up real quick if your trying to shave them.

but if your not willing to come up to the shop, your idea really isnt that bad. after you get the holes covered up from the back, use a stranded fiberglass to fill the front to get the best hold, itll prolly crack over time though. but will be strong for a while, we like to weld the back, and weld the front, grind, then wipe with metal glaze smooth if there isnt any large groove. slick when its done.
