I recently repaired an aux aluminum tank on one of my pick ups with fiber glass. Cleaned tank real good with wire brush wheel on an electric drill. Next painted area with resin, then applied fiber glass fabric, painted with resin, one more layer of fabric and resin. After curing, painted the whole area. Is still working 5-6 months out. But on coach tanks, I might consider taking it to a welding shop & having a new bottom or at least a large patch welded over the leaking area.
