the delux polishing kit i am about to order comes w/ 500mL bottle of UPP, PP and MP, and i was also going to seperately order a 500mL botle of glanz wax. Is this enough product to tackle at least my three cars? 99 Suburban, 99 Audi A4 and 94 Ext cab silverado? the paint is pretty good on all three, light swirling for the part a bit heavier on my truck. is there a chance i could run out of product or will i be ok for this first round?
