Teflon bunk pads

[OilFieldMan]

I've been doing some reading about Teflon pads and stumbled across this brand

I'm having a lot of difficulty loading and unloading my 23 scepter and the idea of being able to push my boat off the trailer in less water is very appealing. In less water I won't have to worry about the stern floating forcing the forward portion of the keel to thump on the cross member.

If I were to install these I know the hazards of sliding off the trailer and would take the proper precautions to prevent it.

What I'm curious of anyone run into problems with hull damage or anything ?
