Optimum Gloss Coat over Xpel Ultimate

[dvazriel]

I am getting my front PPF-ed and while I would love to keep using my Wolfgang 3.0 Sealant on it, it appears is no bueno due to having petroleum distillates, etc.

I have some Gloss Coat left from a previous car, can i apply it over the Xpel? My google searches results are pretty old and they only mention the older Opti-Coat.

Also considering CQ UK3.0 but unsure if it will affect the self healing of the film since it appears to be "harder" than Gloss Coat.

Alternately, I have Wolfgang Spritz sealant - seems to be water based so it should be safe on the PPF?

Will be fine. You are right that it does not harden like UK. If you desire a coating for PPF then Cquartz has Skin and Gtechniq has Halo. I know CarPro states Skin will not impact the self healing of PPF. I am not sure about Halo or even Gyeon's PPF coating. I suspect they state the same.
