Gelcoat is tough to work and tough to apply outside of a mold with a smooth finish. Gelcoat is an air inhibited cure meaning it has to be sealed off from air in order to cure.
Matching it color wise, and getting it smooth, are very hard to do and it usually requires a lot of wet sanding. In order to get a thick enough base the first two coats should be applied un-waxed and allowed to partially kick off then a final coat of waxed gelcoat needs to be applied so that all three coats can cure.
After cure you begin the tedious task of bringing it up to a smooth finish that matches the rest of the hull without the roller or orange peel marks. If you have low spots, that get sanded through, you must go through a thorough de-waxing, even after sanding or any subsequent coats of gelcoat will not adhere.
Applying gelcoat, outside of a mold, and getting a smooth finish, is more of an art form than a "project"..
I actually re-gelcoated the cockpit of my old Catalina 30 and it was quite time consuming..
