Gtechniq C1 overcoated with 2 coats of Exo is great. Application is a little tricky, and if you screw up the you need to re-polish the panel and re do the process. It does not like water less washes as I have experienced so far. Probably best to use the wash sold by Gtechniq.

22PLE is super easy to apply and if you screw up you just use some more to correct it.

Cquartz is easy to apply and they have their own car wash for the coating. The car wash is also used for washing other coating manufacturers product. The coating can also be used on more than one surface.

It is just my opinion that once you have the paint correction done, it is best to use the family of products of the coating you plan to use.
Here is another coating site to have a look at.
