repainting- OEM Rally Wheel color- opinions?

My friend just repainted some original paint 71 Rallye rims.

Krylon Dull Aluminum was a dead on OE match. Problem was finding it.

If you want the paint to last longer, heat the rim in an oven at 200 degrees for 20 min. Gets the impurities out of surface. Paint and put back in oven between coats. After final coat heat to 300 degrees for 45 min. Should be about bone dry. Extremely more durable than paint at room temperature.
