Yes maybe Schuey, I got it last summer and normally put on a new coat every 6 or 8 weeks. I have also used it on my wheels.
So that means about 6 coats or so based on 36 weeks & you have used 3/4 tub?? That's a lot, I would say it's a case of applying way too much......... Also check your frequency, if the car is 'beading' ok ,then no need to wax it. Some guys on here use quick detailer when no waxing is required, Dodo juice does a version of this as well as AG fast wax.
For wheel wax try poorboys, I think that's the one Guy recommends?
