Custom/Hybrid Hull prep for areas to be covered by turf

Simple enough -

I have a pretty much bare hull that has lots of fiberglass work done on it. The tray area and bond rails are completely fresh biaxial fiberglass.

I'm about to start the finish sanding process and I'll then proceed to a marine 2 part epoxy primer and finally paint and sealer.

What kind of prep should I do to the areas of fresh fiberglass that I know will be covered by turf (i.e. the entirety of the tray)?

-I've gotten opinions saying I should just leave it bare - no primer or paint - and turf right on it.

I can easily do this during the paint stage, I just want to know the best approach that will balance out the following:

-> hull durability
-Will I get more water intrusion into the tray if I don't primer/paint it?
-> Turf adhesion
-I'm assuming that turf will adhere better to semi rough glass than it will to finished paint

Thanks!

As long as the fiberglass work in the tray was fully wet out, water shouldn't affect it. Sand/scuff anything that you're adhering to. Just like painting, the turf will adhere best to a prepped surface.

As I'm in sanding mode right now preparing for paint, I'm finding little air pockets every once in a while - for the exterior of the hull I'm patching these properly - but since I'm not going to do much/any prep work in the tray I can't guarantee that it's all sealed.

What harm would it do to prime and put a sloppy coat of paint on the tray in terms of reducing adhesive bonding for the turf? My primer is interlux interprotect 2000E which is a two part epoxy primer. Could I possibly just get away with priming the tray? I just want to make sure I seal everything the best I can, and I can't say with confidence that my tray is sealed completely.

I would mask the tray unless you are not planning on turfing until the paint is fully cured, the glue will make the paint gummy and will not stick good.

What would be the best adhesive to use. Contact cement or is that old news

DAP weldwood contact cement. The red can. You can get it at Walmart or any hardware store. Put a coat on the turf and one one the ski when it's sanded and cleaned and once it gets tacky on the turf and on the ski, put another coat. And once that gets tacky on both place the turf down. Be real careful cause as soon as the turf touches the ski it won't be coming off. Use a heat gun to make the turf more plyable around bends and corners. Just paint the weldwood on with a brush.
