Yes , I did whole frame and under body of a 37 Plymouth coupe I had. Great stuff hammer hard. I don't know what all you want to know. Basically you get it on ya ,you wear it for along time. You can spray it but I don't recommend it, brush or roll. read all the directions and take them literally. Don't paint out of the can, pour some in a container as it starts to dry as soon as it hits the air. I put a piece of plastic wrap over the opening then put the lid on this helps keep the air out. Por 15 has no UV guard , ok for chasis but anything out in the sun will need a finish paint over it. Other then that pretty straight forward . Wear latex gloves . Good luck
POR 15 is paintable. I would scratch it up a little but not really necessary.
