Hi, There have been a couple discussions on the board lately about the finishing of some of the brackets on the undercarriages of C2's (may be true also of C1's and C3's) dealing with the zinc chromate green primer. With the EPA warnings about using paints containing zinc some of the "good stuff" is getting harder to use or find. I came across a spray can of SEMS brand Zinc Chromate green primer and wondered if anyone knows how close this is to the original primer used. The can is over at the shop but I will post the number later this afternoon. Thanks for any input. Shooter
