Welcome to Detailing Bliss klm
Now first of all Integras are one sweet vehicles, I owned an RSX Type S a few years back and wished I kept it but even now I still like the shape of the Integras..
...any who regarding your question, you can use sealants as well. I personaly love wax but just becuase it has no clear coat dosen't meant you are limited to what you can put on your vehicle for protection....but that's just my opinion.
Just curious what wax are you using?
