If you want a durable, and super high gloss, you can use Meguiar's NXT Tech wax (since it's synthetic, it's pretty much a sealant). I personally did not like it. It made my paint too mirror like. It lasted a long time compared the Meguiar's Gold Class wax, but I just disliked how it muted the mica. To be fair, I never used polish when I tried the NXT wax.
