Engine painting

I also used por 15 on my k frame with a brush and it turned out great. I found it to be very tough. It takes about 24 hrs for it to totally dry but well worth thr wait. After me k frame was painted and back in the car and moter installed, I put a floor jack under the k frame and jacked the car up. After I was done I looked at where the jack was and no marks, not even a scratch.
