Anyone interested in 83 Pace Arrow Tear down and Rebuild?

Aluminum will corrode, fiberglass or plastics will not.

I have built "touch tanks" aquariums that hold hundreds of gallons of salty brine water for sea creatures to live in where people can have hands on experience with them and they have not deteriorated over many years of use. Build a tank the size and shape desired out of exterior plywood and use chopped fiberglass and marine epoxy.
