Default Nitro on cars

I was watching a car show today were some guys were restoring a car from 1937.

When it came to specifying a historically accurate paint, they chose a nitrocellulose lacquer. I knew that old cars were finished with solvent paint “back in the day”. But I never thought of nitro as something that would hold up to the weather. I guess maybe the pigment helps.

I do believe that was what the product was first used on, cars, starting in around 1920 or so and the guitar industry adopted it about '25.

Nitro was developed for commercial use and specifically with the automobile industry in mind, in the early 20's by an employee of DuPont. GM started using Duco on almost all vehicle models a few years following that...1924/25ish.

See there? Now you know why those old cars sound so nice.

Yes, and the "custom colors" used on Fender electrics during the pre-CBS era were all auto paint finishes. I think there are web sites that'll even tell you which auto makers and models originally offered the colors I think of as "electric guitar colors."

Nitro didn't hold up well on cars. In general modern car paint tech is better by far.

If often doesn't hold up well on guitars either.

The auto industry didn't use nitro for very long due to the yellowing and checking. It breaks down fast in sunlight.

They may use nitro as a finish when they restore an old car, but I don't think you'll find too many restorers who will go to any great lengths to preserve an old nitro finish. They sand it off and re-do it. You'd be hung, drawn, and quartered if you did that on a '30s Martin. The car guys are more realistic than we are.

Yeh it does not last well in rapidly changing weather conditions.

The show would have likely been doing a concours restoration, these guys that restore to this standard are in a league of their own, every nut bolt washer has to be period and factory correct

Ahh, mid 70's and up Camaro (or Firebird). I have cut wayyy too many quarter panels off of cars in my auto collision days. I can even remember a few full size van side panels. Talk about a bunch of spot welds to cut and dress for the new panel. Ugh.
