>The casting is stripped and glass beaded, any suggestions as to primer under the paint? I am of the perhaps old-school opinion that the best primer for bare aluminum is zinc chromate. However for environmental reasons this stuff isn't as easy to find as it used to be, when every hardware store carried it. It's probably available from specialty paint stores, however. Interlux makes a primer for Brightside and Toplac but I'm not sure if it's intended for metal. You might check the Interlux website about this or contact their local rep or the customer service folks on the website. ______________________________ C.

Another alternative is to coat it with epoxy, and then paint it. WEST SYSTEM sells an aluminum etch kit that you pre-treat the surface with before applying the epoxy. You can also add pigment to the epoxy (white, black or gray, if memory serves) to aid in color coverage when you paint with either one-part or two part paint systems. Gougeon Brothers has instructions on their Web site: www.westsystem.com. No connection to WEST SYSTEM other than I used to work for them in another life!
