Well, thanks guys. The Webers were dismantled almost completely, and the bodies were soaked in a gallon can of carb cleaner overnight. Then they were brushed with a stiff nylon paint brush and rinsed with water. I then chased all the ports with compressed air, and then prepped for paint with brake clean spray. Once they were dry, they were painted with Duplicolor Aluminim Brake Caliper Paint. I love that paint for anything aluminum. It looks like fresh cast aluminum, takes heat, and chemicals. It also keeps the Webers from pitting. The intake was soaked, brushed, and coated with another one of DupliColor's products. Cast iron high temp finish. Although I love bare clean aluminum, I can't stay on top of the pitting up here in the moist climate. Paint is the solution. I used Weber rebuild kits from Redline for the replacement parts. I was specifically looking for a THIN undercoating that goes on like paint. I hate the thick gooey stuff and I don't need it since my Z's are fair weather cars. I found that CarQuest rubberized undercoating fits the bill perfectly.
