Body care and fake tan help!

1- I get really bad, strawberry legs and use glycolic acid every other night to combat it. Will that end up being a problem and cause the spray tan to become splotchy on my legs?
2- I also use an African sponge to provide exfoliation when I shower. Should I change that?
3- I typically get my legs waxed twice a month. Will that cause issues with the spray tan?

Thanks for the advice in advance!
