I used to use paste wax on my old pink Formica bathroom (original from 1950's). This is a great tip. Wax makes surfaces waterproof, also drys to a nice shine.

How clever! Could I use Turtle Wax on a ceramic tub? How about fiberglass?

Most auto waxes contain other stuff including silicone .
Does it make it slippery under foot ??

I used auto wax for years. Yes it makes the floor slippery. The first time I fell and banged my head. I've been a cranky, ill tempered curmudgeon ever since.

I dont do the floor,But it really makes the fiberglass tub pretty ,protects it very well.
