I have painted the spots on my green kettle and blue SS with some success (not exact color matches by any means), but I have not needed to paint a red yet. I sprayed the blue with 1200 degree manifold paint, then 500 degree engine paint (because the color was closer), and it has held up without a hitch so far on both the bowl and the lid. The green was painted with a 500 degree grill paint and while it is starting to pop off from the bowl, it works well on the lid.
