this may be a stretch but after seeing some of the offbeat color schemes on car bodies I was thinking of getting a 1/24? plastic model kit car & painting it various combos to see what scheme/color grabs me & I suppose a person could do that with a model engine also (I'd want a bigger model eng). As you know when the time comes triple clean all surfaces & I do a final cleaning by drowning the surface with brake kleen, gets onto the rough surface pores on blocks/intakes etc.
