Like he said, Eastwood's Shadow Blue was a good match. At the time they also had a free shipping deal > $50 so I got the SEM cleaner, PRE and and a satin clear for a top coat which gave close to original sheen of OEM blue plastic parts.
Most local auto parts stores and also our local Body Shop Supply also carried the SEM dyes. If I had not been buying into the SEM regimen for prep & paint local prices would have been convenient and reasonable.
