Now the good part is I sprayed the calipers with this paint and it's a great match for stock color, so much so I applied it to the clutch control , master cylinders, handlebars, headlight bracket and fork legs, looks fantastic.
It is pricey, $21 a can but it is reported to be fuel, ethanol and brake fluid resistant once cured.
It's the POR 15 Chassis paint, dries to a nice satin finish.
Here is a picture of the fork tube.
