At the local auto store find NU-FINISH sealant. It's a quick and easy way to get a decent shine that will last the season.

You can apply by hand, but better off using an orbital buffer. Harbor Freight has a decent buffer at a reasonable cost. Try the microfiber bonnet and see if you get a good shine. If you need a more aggressive cut to achieve a shine, use a wool bonnet. Both available on Amazon. Buy a lot of bonnets, they clog up quickly.

Personally, I prefer 3M polishes. For mild oxidation I use Perfect-It compound follow by Finesse-It and use a good sealant such as West Marine AFP liquid Wax. If there is no oxidation, skip the Perfect-It step. The sealant should provide UV protection. A major reason why gel coat oxidize.
