Gelcoat will run you around 50 bucks a gallon and they carry cook gelcoat so its really nice thick gelcoat not the cheap stuff. It covers 1 coat around 100 sqft. I would sand everything down fill everything then gelcoat it. If you have axcess to a cheap spray gun they have a product there called duratec its a high gloss additive and you mix it 50/50 with your gelcoat to shoot it and it comes out really shiny and nice. Do not thin your gelcoat with styrene or any other product it is the old school way of doing things and you will ruin the integritiy of the gelcoat and later on your gelcoat will become chaulky and will have no shine. Give Danny a call at the store hes always willing to help people with there projects there # to the store is 772-464-0808 and i believe they have a website also you can order materials fiberglasssupplydepot.com. Let me know if you have any ?s about my project or anything ide be glad to share what danny has taught me. I will be posting my rebuild soon.
Duratec has some of the same negative effects as the other thinners, especially when mixed at 50:50. Gel coat covers 80 sqft per gallon at 20 mils, you will need more than 20 mils to sand out the orange peel. Factor in the cost of sand paper and the time to do it and paint becomes very attractive, even more so on something like an old canoe.
