No. Follow Malcolm's words of wisdom. The manufactures know a thing or two...

Brightsides is a pleasure to spray. HVLP gun, a bit of thinner and a dust-free room = mirror finish (the dust-free room is the tough part). Brightsides is nice because it doesn't have the isocyanates like Perfection, Awlgrip or other two/three part urethanes. The downside is it's not as rugged.

The last time I used it was back in the spring of 2008 for the deck on a customer's Njord. We blended white and medium blue for a custom hue.
