Just for note really, performance white marks very easily, even with the natural oils from your skin sometimes. However, nearly all marks burn off and disappear once the manifold gets up to working temperature from some full throttle.

Even made a mess from a nylon fleece by leaning over the bay and that disappeared. The only stuff you really need to wash off with soapy water is oil that's more than a few droplets.

The colours that Zircotec apply are on top of the coating and provide a finish that's easier to keep clean. The extra colour layer doesn't make any difference to the performance of the product.
