For power transformers, filter chokes, etc., most of the time I use Krylon Satin Black. For the 655, noticing the 655's interstage transformer had the remants of gloss black paint, I had some leftover Dupli-Color gloss black auto touch-up spray paint and used this for the power transformer, filter choke and interstage transformer.

I usually run any radio I am playing for hours at a time through a bucking transformer setup, dropping the line voltage to 110 so the power transformer only gets lukewarm. I would think that if you need high temperature engine paint designed to withstand several hundred degrees Fahrenheit, that your power transformer is running too hot!
