And that is why I would never use 5200 for anything on my boat! I have and I'm sure many here have also damaged hull and deck glasswork when trying to remove a previously bed 5200 item. I don't have the numbers in front of me but 5200's breaking strength is much greater than fiberglass. According to the manufacturer it is a PERMANENT adhesive. In my humble (depending who you ask) opinion, NOTHING on a boat is permanent!
Yes, there are those who say that 5200 has uses. So, I have to concur that if I had a 16 year old daughter, I may consider using 5200 to "secure" her bedroom window lets just say from stray drafts.
But thank god I don't have a 16 year old daughter!
