I use Wolfgang sealant. It lasts a reasonable period of time. It's optically pleasing and easy to apply and remove. The more layers, the better it looks. Zaino products are another good choice.

Really though, you'll get a lot of recommendations of different products. There's too many good ones to list them all.

Whatever you decide on it's worth your time to learn to use a clay bar. Mothers and Meguires both market decent clay that's effective without being too aggressive. Buy whichever one is cheapest. Wash your car with Dawn dish liquid and use that same Dawn in a spray bottle no more than 20 to 1 mixture for your clay lube. If you drop the clay, throw it away. Best not to drop it. Only after this will you really be ready for sealant or wax.

Once you've sealed the paint only use a good car shampoo as it will not remove the wax/sealant like Dawn and other alkali detergents tend to. Always use two buckets and dry with waffle-weave towels. Blow excess water out of tight places with a leaf blower.

HAVE FUN!
