Paint Removal by Electricity?

[mivey]

I have a perfectly good 22ft aluminum V-hull. A starcraft w/chevy staight-6 Mercrusier inboard. It Hauls ten drunks while pulling a saloam skier, and gets good milage. It has sat in a garage for 12 years (small children and other problems), I finnaly recommisioned the vessel this summer HOORAY!!!. I have noticed that the boat leaks at a concerning rate. Could the seepage be to haveing sat idle so long?? Any suggestions?? What are my options?? I think that the seams or rivit joints have "shrank.

Raise boat. Flood with water to finds leak points, then:
Tighten rivets
Replace rivets
