Ok this is for a '72 chevy truck not a boat sorry, ok so can I powdercoat a set of truck headers or am I wasting my time and money? I know they get hot cuz they are in a truck, i don;t want to spend the money on ceramic, will powdercoating last?
Unless something has come out lately, powdercoating will not work on headers. I had a set done in the early 90's and they cracked and peeled. Lasted about as long as paint.
Jet hot is the only way to go. Awesome stuff.
