This is my first boat, it's a 14 foot fiberglass Glass Glide jon boat made by the Seminole boat company of Willacooche Ga. It was my Dads boat and I want to repair it! The back seat ( all fiberglass) was worn out. I cut out the bad area on the back seat which was about 12x32. I filled the void with styrofoam and great stuff. I then put a sheet of metal flashing across the top and a piece of 3/4 inch pressure treated plywood (9x24). I used bondo - glass to fill in the gaps and I plan on using fiberglass cloth to finish the seat. I am sanding the inside of the boat. I then plan on turning the boat over and tackling the bottom. There are several places that you can see torn fiberglass (mostly on corners and edge's) I suppose it's gel-coat and I need to know how to fix the bad spots and re-paint the bottom. Any advice will be welcome..Thanks! Ken
