Nuvite and Cyclo polisher. Mine started with same years of unpainted neglect. Lots of work and paint on sections I didn't want to polish - fuse and wing bottoms. Then finished off with a paint job similar to Scott Yoke's Quick Silver P-51.
Like the outcome, but know that you'll never be done once you go down this road.
Privileged to explore the world in the venerable Lockheed C-130 and the regions around NC in a work-in-progress RV-4, kit #2614.
