We had the paperwork from the repaint done by the previous owner. There was no paint code/type listed, so we contacted the body shop. Unfortunately they had changed management and the records for this work were not available. There was no way to know if they used the OE formula or even what brand was used. So it was paint match time.

I used a side marker light housing as the sample and a local paint shop who specialized in classic cars matched it for me, a single stage urethane. It turned out really well in the end, but much anxiety was involved.
