Waxoyl advice... Inside doors?

[supercharged spaniel]

Right got two fresh doors ready to go on and I'm not sure which is the best way to protect them. I've got some clear waxoyl spray with nozzle and was gonna fill the insides of the doors with it? But my mate reckons this will block the drainage holes and is worse? What do yous reckon?

Once the Waxoyl goes off its rather like a softer beeswax and will be easy to poke out the drainage holes again..
