+xI've used tygavax tygaflor and tooltec for use on mdf and wooden plugs, it's a self adhesive ptfe tape and works well, but it ain't cheap.
As you are aware the wood soaks up anything you put on it, I know people have used wax through to 2k lacquer. The key is to make sure the coating is cured fully and compatible with the resin system you are using
You should do your own small sample test of the materials and release agents etc.
