Trex tells me the transcend product on 16" centers is fine but no installer will do that for me. I get it, they don't want guarantee a deck that they don't build the frame for.

I'm happy to do resurface it myself with that product but don't want to spend the time if its an issue. I've got 750 sf of decking and can't get anyone with real world experience to weigh in on this. Any help?
