yes it is powder coating , we just call it stoving over here for some reason true stove enamelling is too brittle ive some old stoved camping metal crockery that are tough , but can chip, would be too brittle for bike stuff, avoid plastic coating tho, if that chips rust gets underneath and it peels , with powder coating you can touch it in, incidentally my r65 is 100% original finish apart from the seat which was rock hard and damaged , my frames showing some return to ferrous oxide! but i want to ride it not restore it! (yet)
