Coolus Finish

[Jeffrey Hildebrandt]

Lacquer will keep oxidization at bay for a long time, but it isn't great for armour because it scratches. I second Alan's recommendation, and would suggest furniture stripper to remove the lacquer, and any polishing paste to keep up the finish. Tarnishing can be minimized by wiping the helmet down with ethanol after handling, and a layer of conservator's wax (like renaissance wax) will keep it in good order during storage.
