which orange block paint??

make sure to use a primer base clear for best results. and clean the crap out of the metal before you put the primer down. I painted a 318 with the dupi and it all flaked because I didn't prime it, since then I have learned and all my motors look great. Also follow the instructions apply all coats within an hour and if you miss the window wait 7 days, The paint will peel and bubble if you don't and is a real pain to get off. It is good stuff an a lot of the shops around here use it.
