The paint system for the new auxiliary counterweight system components will include an inorganic zinc-rich primer, epoxy polyamide intermediate and an aliphatic acrylic top coat. The owner-approved coating manufacturer is Carboline or an engineer-approved equivalent.

The new skew resolver components will be coated with a high-gloss oil-resistant paint for external use and resistant to weathering and abrasion. The coating system will consist of one coat aluminum epoxy mastic primer, and two finish coats of an aliphatic polyurethane. The owner-approved coating manufacturers include Carboline and Sherwin-Williams, or an engineer-approved equivalent.

The threads of all mounting bolts and fitted bolts will be coated with an anti-seize compound before assembly to prevent corrosion or galling and to facilitate in future removal, if necessary. The owner-approved anti-seize compounds are A.W. Chesterton and Henkel Corporation.
