I've done this once before with a Stargate and am about to do the same with a moon patrol. I used an adhesive remover as purchased from Menards. It does smell up the place a bit, but it works. I believe I used a heat gun to soften up the adhesive securing the old CPO initially. After removing, then you paint on the adhesive remover with a brush, let it sit without letting it dry and use a putty knife to scrape up the adhesive.
When finished it might not be a bad idea to let it sit for a couple days and gently sand the surface a bit. A little wood putty in spots. Throw on a coat of Kiltz sealer and a coat of black enamel.
That's probably going overboard but the wood is thoroughly protected.
