Use salves and things on any marks. I spank mine a lot and have never had problems but then I know what I am doing and pay very close attention.

Some of the more extreme ways of leaving marks can cause a lot of trouble. Those should be avoided or the very least done infrequently. These in my opinion would include bullwhips, canes, narrow paddles, split bamboo, and abrasions devices. Use them sparingly if you enjoy them with lots of after care
