Jim- Yellow zinc sounds good. If I understand that coating correctly, it takes rattle can paint fairly well (so I could paint them blue to match the rest of the calmini stuff?). If yellow zinc can be painted over, then I'm all for it.
A chance to influence the market...hmm...can we talk you into making a mechanical locker for the Xterra?
Say the word and I'll start dialing the phone right now!
