I am having trouble deciding if por 15 has changed. I used some years ago and the stuff was nasty to work with, but I felt it would do the miracle job kinda that they suggested. Now I go on line to purchase some, and I get confused with all the choices. Do they have the original and simply just more choices? I thought they called it rust encapsulator and now I see it is called rust preventive. Does someone know what number it would be for the original or am I making this difficult?
