What type of finish does PRS use on CORE guitars?

From 1985 – 2019, PRS used a polyester basecoat and an acrylic topcoat. During 2019, we started to transition to a nitrocellulose over CAB (catalyzed acrylic) finish. This was a flying change that was slowly worked into production. If your guitar was made during 2019, we cannot accurately determine the exact finish used on your instrument, so it is best to treat it as you would any other nitrocellulose finish and avoid long term contact with leather, rubber, and vinyl. Guitars produced in 2020 and beyond have the nitro over CAB finish.
