Can you use spray paint in a can from the auto paint store? I have used several different types of spray paint from the can, most have worked others have not? I m using paint from the auto paint store since my OHW ran out and so did my cash trying to finish this nightmare project! And I can't figure out the reason why I keep failing! It appears to be under activation but I am dumping it on at least it looks like that to me! Last dip the film was all over the water I was suppose to have this done and shipped today but could not get the film to stick and help guys!
