I pick up my gheenoe on Thursday from a guy on craigslist. $200 for a perfect 13' sounds like a deal to me. Anyways, I have the ability to cut bend and weld STEEL. I can cut and bend, but not weld aluminum. Is there a suitable finish other than Powder $$ Coat that will protect the steel? I'v used rustoleoum and POR15 on car frames, but nothing that was 100% dedicated to the salt. My other option is to pay someone to weld up my prefitted aluminum pieces. How much does this run? Do they charge per-weld, or by the hour? Any info would be awesome!
