I am planning to put mastic tape or paddle guard on the paddle for learning

Tape on the paddle is a forever thing. You don't stop taping the paddle once you get good at paddling.
The reason is that it is too easy to damage the fine edge of your $600 carbon paddle on almost anything it comes in contact with. Paddling skill has nothing to do with it.
Banging a rail in a wipe out, knocking the paddle against a rock or the door of the car or the garage. Having it fall over when leaning up against the wall can all ding your expensive paddle.
With practice you can do a fine job of taping the paddle in just a few minutes. You don't need to put heaps of tape on there or make a big job out of it.
Dinging the rails should be less of an issue. Certainly tape the rails if you want to.
Some of the early boards had poor resin formulations and they would chip very easily. A modern board should be able to stand up to almost anything you throw at it.
