Bed liner on plywood?

I also used closed cell foam weather stripping on the back of the drawer facings, which I glued on with a thin film of construction adhesive, leaving a 1/8” gap at the center of the bottom section to allow any water to escape in case some found a way in, which so far hasn’t happened.

 

I am thinking of using Herculiner for a slide in box/camper for my utility trailer. It works great with wood from everything I have googled on the subject.

 

Since you bumped this and I was digging around on google and found this, I’m wondering if anyone tried a primer prior to coating plywood with bed liner or has a suggestion for a primer that’ll work as a good base.

I want to use Baltic birch (very flat, high strength/ply count, no voids in between the ply’s) for a truck bed base inside a wedge camper buildout and plan to use Monstaliner on the plywood and other places on the truck, but don’t want to buy/apply the bed liner until everything is ready, lots to complete before then.

Hoping to use the primer as a stopgap/protectant so I can run the plywood for a while.
