Aervoe insulating epoxy was originally used on electrical windings just like Glyptal, across the years engine builders have found this to be a wonderful solution where engine presentation is critical.  It also has the benefit of creating a tough flexible coating that is highly adherable to cast iron, while improving oil flow and decreasing porosity due to the coating nature.

This auction is for a single 12.5 ounce can in aerosol format. No mess, no fuss easy to spray aerosol unlike a brush on.  Also good for vehicle undercarrriages to produce that "red oxide" type finish.

Pictured is a raw cylinder head and the same cylinder head with the Aervoe epoxy coating.  The picture was taken in the sun and was one single pass.  The epoxy finish is great for cylinder heads, intakes, timing cover and blocks.
