I noticed on my last trip that I had a lot of water in the bilges and after an examination of the hull I found a crack that had opened up in the glass where there had been a previous repair (previous owner). So I ground away the 'bog' or what ever they used and opened up a hole (I probably could have been more careful).
I have some two pack type fibreglass based body filler that I was going to use to repair it but was wondering if I should use something behind the hole?
Any advice would be appreciated and smart-ar#ed comments are encouraged.
Peter.
