Yes, Motor Coater works well on spindles, upper A-arms, and other suspension and chassis parts. It is an exterior-grade, UV-stable coating that adheres to a variety of surfaces and holds its show-quality finish outdoors.
For spindles, A-arms, and similar suspension components, most builders prime prepped surfaces with RustSeal first to create a permanent rust-proof foundation, then top coat with Motor Coater for the final color.
For extra durability: On parts prone to rock chips and road debris, some builders let Motor Coater cure fully (7 days) and then add a top coat of DiamondFinish Clear for added scratch and chemical resistance. DiamondFinish Clear is formulated to apply over cured single-part (1K) paints like Motor Coater; follow the DiamondFinish Clear directions for full application steps.
For full surface prep, coat counts, and cure times, see the complete Motor Coater Application Directions.
