I've tried taping inside corners, wiping off with a wet rag... Neither seems to work particularly well. I saw someone indicate they waited about an hour and then scraped off the excess in glue ups. Seems like a reasonable method, so here's my question... Is it OK to remove clamps after an hour? I recognize there are significant benefits to substantial clamping pressure, but how long do the clamps have to be attached to attain those benefits? I've always left 'em on overnight, but I'm now wondering if I really have too...
