Grats on the PC, did you get pads and a backing plate also? Orange and white?
Anyways, the Zymol wax at wally world is made by turtle wax, and it sucks [censored]. Smells good though.
Alot of companies misrepresent the word polish. Zaino uses it on their sealants, megs uses it for a glaze, and as you see you are assuming polish because the zymol wax from wally world is a cleaner wax.
I wouyldnt spend the $$ on the real zymol until you have clayed(above the surface contaniments), and polished(removed below surface defects) the paint. I have maybe 35 bottles of all sorts of different polishes, and to be honest, depending on what your paint looks like, i like 205 or scratchX 2.0 for you. If your finish is more neglected i would venture to say use the Ultimate Compound, but take it slow with this and check your work if you are using a PC. PM me if you need any help.
