"Did some research on the paint color of the MDS888 and figured out it was almost exactly the same as Sherwin Williams Polane-T Nitro Blue. This just happened to be the same blue that I had my paint vendor use on a product in the 90s. Got a few oz from him along with catalyst and did some touch up work. Perfect match." - Roger Arrick, rogerarrick.com
