I used the Bill Hirsch stuff for my '52's 235 because I like the shade, it seems a little darker than most of the engine gray rattle cans I've found. If I had to do it again though, I'd use Rustoleum Charcoal Gray rattle can. It's on the transmission below. Different camera metering indoors vs. out, but I can tell you they're pretty similar, with the RCG being just a tad darker. Very confident the Rustoleum will take the heat of the engine as well. Have had nothing but success with Rustoleum.
