I am currently replacing my transom in my 1990 Stingray 17 foot boat I cut out new transom wood and I thought I could use 5200 to attach it to the fiberglass. I spoke with a boat repair place today and he said I need to peel it off and fiberglass it on. Which means I pretty much have to start over. Do you guys see any long-term problems by doing what I've done?
