Probably the best advice I can give is to use a good product. Dupont Imron clear is what was recommended to me but it wasn't available in my area so I went with what the local auto paint supplier had which was a PPG product. It looked great for several years but then started to flake off again. The clear I used was for cars. PPG did have a product meant for boats but they didn't have it in stock and it was really expensive. If I had it to do all over again I would have used the better product. I found it real easy to remove the existing clear coat with a simple razor blade. Scuff up the old gelcoat to give the clear coat some tooth to bite into, mask, clean, and spray the new clear. I believe I sprayed 3 coats but it will be whatever the manufacturer recommends.
Imron is nasty stuff to work with so make sure to wear a good respirator, gloves and suit.
