Hi all
I've been in the process of painting my engine tins black this week (sandblasted them a while ago but finally the weather is warm enough so it'll dry in the garage). They now look like new again but I am more interested in more efficient heat transfer.
I still have some POR-15 left and was wondering if it is a good idea to paint the outside of the valve covers. If that is indeed a good idea, does it get hot enough where I need POR20 and 15 just won't do? How about the push rod tubes? I guess it doesn't hurt, but does it help? Are there other parts that run cooler painted black?
While I am on this topic, can the inside of heater channels be treated with POR-15 somehow? (besides dipping the whole car in a swimming pool filled with the stuff, that is? :)
Thanks! Remco
