Once I could no longer get product out of my tube, I cut it open, top and bottom, to investigate
what I had read. Sure enough, there was a LOT left.
This is a shot of the inside of the "empty" tube:
This is all the product that I scraped out of the "empty" tube:
The container that I put the remaining Primer Potion in is a 0.25 ounce jar. It filled the jar up and even went over the top a bit. The tube of UDPP is listed as 0.34 ounces. This means that you are getting less than 0.09 ounces of product before the tube seems empty and nothing else comes out on the applicator!
So, next time your tube of UPDD seems empty, try cutting it open and see how much is left. You will be surprised!
