dude polish and wax is different.. wax is applying a layer of coat to prevent water go inside ur paint.
polish is to remove a layer of paint so that ur paint look new.
i wax and polish my wings before. nothing happen.. the layer of wax protect the wing wells. U try to find non-abrasive wax to polish ur car. Turtle wax is a bit strong. I use Kit Wax (for 0-2 years paint) there are also several other type of wax which is suitable for old paint.

paint is waterproof
please get your facts right
wax n polish are different
that much, you have got it right
wax sticks to the paint...but there is no chemical reaction
so it can wear off easier
it creates a slippery coating on the paint so that dirt cant stick so easily
(certain air borne dirt like smog does react with the paint if it is allowed to be in contact with the paint over long durations)
polish on the other hand (most of them these days) actually bond with the paint
so the upper layer (top few molecules) of paint is actually not purely paint
it is an alloy (if you will) of the paint and the chemicals in the polish
this (depending on what the polish is designed to do) can have varying effects on the paint surface
among the effects are:
- to create a slippery layer (same function as wax)
- to create a UV resistant layer to reduce UV damage and thus prolong paint life
- to harden the surface of the paint to make it more resistant to nicks and fine scratches
many polishes (i'd go so far as to say 'most') these days are non-abrasive
unless statedfor old paint, u r refering to cutting agents
these are meant to remove the layer of dead paint
once the layer of dead paint is removed, one should not continue to these cutting agents
one should switch to a good silicone polish which will help to preserve the newly exposed layer of good paint
