Ordered the Whitson Full length rack!
Curious what you painted yours with @Rickashay?
BAMF recommended the Rustoleum hammer finish primer and paint for my sliders. The hammer finish hides minor imperfections.
I've used the Rustoleum hammerite paint lots (sliders) and its the best spray paint I've ever used. It wont compare to the powdercoat but it's a great budget-friendly alternative.
