Ditto here, except that I **have** used the fast-set 5200 to attach D-ring holders (PVC) to the inside of the hull of my fiberglass yaks, and that stuff is also permanent. I use 80-grit to roughen both surfaces, and a clean acetone swab to remove any oils (etc.). Bob, if the foam is delaminating from your hull after adhering with 5200, I bet the failure is in the foam, not the 5200. -- Dave Kruger Astoria, OR chemist *************************************************************************** PaddleWise Paddling Mailing List - All postings copyright the author and not to be reproduced outside PaddleWise without author's permission Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.paddlewise.net/ ***************************************************************************Received on Thu May 18 2000 - 11:39:47 PDT
