I have twin Detroits 6-71's in my 38 Hatteras. I recently had the engine room cleaned and I am now ready to paint the engines. I was told by a friend that I need to purchase a high heat resistant paint, however, I spoke with someone at Valley Detroit who told me that all I need to purchase is the KRYLON 1501 spray at Home Depot. The engine manifolds are water cooled and I dont need the high heat paint. Can someoine help me with some guidance?
