So, I think poorboys is way over rated - I used to use it too.
Like bodywork, it is all in the prep - dirt can't stick easily to slippery wheels... but the difference is heat and hot iron / metal particles flying off brake pads.
I'd swear by a silica nano coating for wheels.
Do a full clean off them, including tar and iron X, IPA wipedown, then Gteqnic or CarPro wheel seals - do two layers once cured.
This will last for 6 months to a year and only need bodywork shampoo and a sponge to remove dirt from - worst case.
A wax will work, but their protection breaks down under such extreme heat - if you wanted to spend less money there are cheaper options like jetseal and fk1000p which are high temp sealants
