Since buying back my old 18' last weekend, I have assessed what I want to do. Among many projects, I will be painting it with Imron since the gelcoat is no longer holding its color and there are quite a few places which need repair. I pulled the engine yesterday - notice the Magnaflow cam driven water pump and and it has an oversize oil pan. Tonight I will be using a trick I thought I would pass along. There are two bubbles in the gelcoat on the deck about the sizes of oblong baseballs. If I just air file the deck to straighten it out, those bubbles will have very little strength and they will probably continue to grow in size so they need to be filled. I drill a small hole in the center and a few very small holes at the outside perimeter of the bubbles only as far as it takes to get to the air gap. I then use a plastic squeeze bottle which I use to force the catalyzed polyester resin into the center hole until it comes out of all the smaller holes. I have some squares of wax paper ready with tape on them to place over the holes until it has hardened. Bingo - bubbles are filled and ready to be sanded for paint. I will be using the same color red and white that it came with originally - no more compounding! Bill
