will lift the oil out of the wood. Spray it on, let it work and then brush it off. The oil on the servos won't hurt, they're pretty well sealed.
Use your heat gun to heat the wood between applications of the K2R. This will force the oil out of the wood. Then apply the K2R to soak that oil up. Keep doing this until you start seeing little or no oil being forced out of the wood when you heat it. The get the wood as dry as you can and seal the wood with epoxy.
