My first thought is the product you are spraying has outlived its shelf life. I know for my self it's rare that I still have good spray able hardner/activator by the time I get back to a project a second or third time. I'm not familiar with the "Purple Gun" but use the cheap ($20) Harbour freight many times. Since my tools or product set, I always spray some thinner or reducer through the gun first to make sure its working. Usually I just spray against a piece of paper or cardboard for a test pattern. Only after I'm confident in my spray gun do I mix product. It's very difficult to seal up a can well enough to save it for another day. Here in Indiana if evaporation doesn't ruin it the humidity can. In the old days you could just add a little thinner/reducer to make it spray able again. But now days the products need to dry chemically instead of air dry so I don't think that works. I hope this helps.
