Although my good buddy is advising against doing this in order to keep its historical Mojo, I am looking for a safe polish for my new-to-me '81 L-2000. Just got it at a guitar show, it's really gunked up, especially the neck, with who-knows-what and other people's DNA.
From another TB G&L forum I had read that you have to be careful with these finishes, and sure enough this is what one manufacturer came back with:
Nitrocellulose finishes are very finicky. Therefore, we recommend you test any products from our Formula 65 line on an inconspicuous area before applying it to the entire guitar.
If you are going to use the product please be advised of the following: If there are any cracks, chips and or checking DO NOT spray the polish directly on the finish. Doing so will cause the polish to get under the finish. We do recommend that you spray a small amount onto the polish cloth and polish the finish.
For those that have one of these older models, what are you using to clean or polish it?
