I did not know what work went into this untill my brother stoped by to lend some advice. The bottom had been redown when I bought the boat 2 years ago. Well it seems that the glass was laid, whomever did it, did not prep the bottom enough and you can pill the stuff right up. As I stand right now 3/4 of the bottom has been pilled off. I have to grind the other off with a grinder. The plan is to finish getting the old bottom off and lay at least anoth couple of layers of glass on it. I also bought an epoxy called coat it to apply after the glass is laid. I will post pictures tomorrow of this project as it is now under way and there is no turning back! Wish me luck!
