I can tell you I am not happy with the Dupli-Color paint I used on my eng this time. Course I had the same problem with the MP paint as everyone and I liked the color of this Dupli-Color as they call it Hemi Orange. I put this eng in the car in 2011 and the paint held up ok for a few years but the last year or so its started to peel in spots on the intake , heads , oil pan and block a little. I touch it up where I can get to it and even use a brush in some spots but I am not happy with the Dupli-Color and wont use it again. I prepped my block and parts like I always have and I have had good luck with eng paint until I used this Dupli-Color this time. Heck I might pull the eng just to repaint the whole eng this winter.
