car polish finish

Just after some advice on what would be a good car polish to try as a finish over top of a cut back (with wet and dry ) poly wiping varnish to give me a nice shine and finish, have heard Mcguires is a good brand however there are quite a few different types of this brand of wax, just wondering if anyone has tried this finish and would recommend a certain type of car wax over top of poly.
I am also wondering if you would get any stains from coffee cups etc. as it is a finish for a redgum table top and needs to be as hardy as possible. Thanks in advance:2tsup:
