as a cheaper version of lube, try:
snow foam or generally shampoo the car first to get rid of the dirt and grime, then once the car is clean, although still wet, lightly snow foam or soap the car again, and clay the car then, so you dont have to use all the quick detailer, as it does not need the quick detailer for lube, it can technically be anything soapy acting as a car lubricating product for the paint work
once this is done, I then give the car another quick rinse and then start with the quick spray detailer etc
