best product for swirl removing ?

g35300mm

I bought this Simoniz Applicator kit for my orbital buffer and it gave me;

4 Terry cloth bonnets
1 Foam bonnet
1 wax applicator (which looks just like the terry cloth bonnet just it doesnt have long threads that stick out)

Which one am i supposed to use to put wax and polish on? its telling me the wax applicator which doesnt look all that great, i thought you were suposed to use the foam/sponge looking ones?

thanks,
