AMEN. Don't know if you have access to a TIG but that would definitely be best. Slow and easy with nice control. Aluminum welding with a spool gun or stick is controlled chaos that takes practice.

With a TIG and a little practice you could make a good looking bead on your boat. Just like stacking dimes.

The church is close, but the road is icey. The tavern is far, but I will walk carefully. -Russian Proverb
