I actually think it looks rather strange painted OD. I think black would look a lot more normal, but per the JeepDraw color reference page it should be OD, so I went with it.
I did a good bit of reading on the net about what is the best paint for radiators. It ended up being rather confusing and there area a lot of opinions out there. It seems that the temperature of a radiator is right around the maximum temperature that a lot of conventional paints can handle, but I couldn't find a higher temp OD color that I liked. It also seems that a lot of people on the net believe that if you use "special" radiator paint, you get significantly better cooling, but I couldn't find any legitimate reference for if that was true other than a bunch of over-hyped sales info.
So, in the end, I decided to go with what appeared to be on the radiator in the first place. I cleaned the radiator very well and put a nice uniform (but thin) layer of OD with no primer. I believe that this is what was on it in the first place, so I guess we will see how it performs. If it was good enough for the last 69+ years, I'm hoping it'll be fine now.
