Joints that defy the largest wrench will open as if brand new. Well, muriatic acid is a very powerful acid, and works well on iron pipes, or copper pipes, but I am skeptical that it is a good idea on an aluminum frame such as the Feathercraft has. Aluminum will react pretty fast with it, unlike iron. I do not recommend using muriatic acid on aluminum. -- Dave Kruger Astoria, OR chemist *************************************************************************** PaddleWise Paddling Mailing List - All postings copyright the author and not to be reproduced/forwarded outside PaddleWise without author's permission Submissions: PaddleWise_at_PaddleWise.net Subscriptions: PaddleWise-request_at_PaddleWise.net Website: http://www.paddlewise.net/ ***************************************************************************Received on Sun Oct 29 2000 - 08:24:58 PST
