i have always built my own engines and painted them with rattle can paint, and there's no doubt you get what you pay for with that stuff just like anything else. the higher end spray bombs definitely cover better, look better and last longer, but still not good enough. i want something with the durability of the original, and the POR 15 engine kit is looking pretty good to me at this point. i used to just thrash my cars like they were terrorists, but this time i'm gonna try to be cool and treat one with some respect, and i want it to make me proud when i open the hood instead of only when i gouge the pedal!
