How to clean gummy haze from vintage Nitro guitar finish

I use Ronsonol or generic naptha to clean and Meguiar's Ultimate Compound and Polish to clear the haze from old nitrocellulose lacquer finishes. Those products and a soft cotton cloth are all you need. A buffing wheel or drill buffing attachment will make this process go faster of course. Careful with a buffing wheel though, nitro can heat up and melt easily, a drill attachment is safer and easier to work with.
