Today's dumb question- PT wood and roof cement

Does anyone know if roof cement is compatible with PT wood? The wood is MCA (micronized copper azole) and the cement is Gardner Wet-R-Dri (all weather plastic roof cement).
The cement spec. sheet doesn't state anything about PT wood, but does recomend it for a below ground waterproofer. Yes, I've contacted Gardner for an answer and haven't recieved a reply about this.
So...who thinks using this tar-like substance on PT wood is OK?
Thanks, JB
Edit:- I'm thinking of building a waterslide also, for the nephews.

I would have no problem using it.

Thanks Dennis. I was just about to try to eliminate this post, seems it's OK to use the two together.
Thanks again, JB
