Nice resurrection

I respectively disagree that paint on the hydro, or any other heat radiating unit, will make it run hotter. That being said is meant in sense that the paint is not gobbed on in heavy coats thus clogging the cooling fins such as grass and grease would do. A light coat of almost any color would have imperceivable affect on the operation of the hydro. I cant argue the fact that hydro's were left unpainted and I don't know the reason, but paints insulating effect is negligible unless it is paint specifically meant to insulate.

Pretty sure it's because of it being aluminum. The cast iron blocks were painted, but the heads were not. Just like the hydros.

Good job Walker, you should come up here n help me with my 18! Cant seem to get time

It's no big deal Lance. ironman just wants to argue because it was me who said it. If it had been you who said it, I doubt he would have bothered to respond. I also doubt he truly has an opinion, or any positive proof one way or another. As of late, the only time he posts is to try and illicit a response from me. Kinda silly really.

You can read all the physics articles or forums you want..... it's not worth the time to debate on this forum. I'm making my argument based on what I've seen. Hydro's are never painted from the factory on any piece of equipment I ever worked on. Combines, sprayers, oilfield drilling units.... all bare metal originally. Has to be a reason, and the only one I can equate is heat transfer. I do agree with him in that it's negligible anyway. It's likely not going to make enough of a difference to be a problem.

In my post I said that I "respectively disagree" with you and I would have done the same with anyone else. Nothing I said was directed personally at you. Why do you feel the need to retaliate.

As far as proof that certain paints do not hinder but in fact improve the rate of heat radiation from metal, simple high school physics experiments using a Leslie Cube and infrared camera takes care of that.

Nothing was meant to be silly, just pointing out the facts.
