Old Testors color chart


Recommended Posts

I would have guessed sometime after '66, the Testors Custom Colors are what used to be the Ed Roth Custom Colors line.  I'm pretty certain the Roth car kits left the Revell lineup after '66, the connection between Roth and Testors probably ended around the same time.

But the chart still doesn't explain what "pla" means.  Some say that it means "for plastic", but the chart states that those enamels can be used on all sort of surfaces.

That was my first thought , too . It's obviously not an acronym ( i.e. , 'Plastic , Leather , Acetate" or some such ) . Maybe it's in the description , but I can't rea that fine print .

And, you won't get a straight answer on the net. I doubt calling RPM to get the skinny will get to the bottom of this, either. The blokes what works there know even less about product history than we do.

I think the only hope to find some definitive answers would be to find one of the early Testors employees (if they are even still alive). Chances of that happening are not very good.

If PLA meant the same then as it does now, it is Polylactide or Polylactic Acid, according to Wikipedia:

https://en.wikipedia.org/wiki/Polylactic_acid

Polylactide is one of the most popular materials for 3D printing, quoting the article.  This article explains how to paint PLA printed items:

Amazon has a listing for Testors Pla 1156 paint thinner:

https://www.amazon.com/Testors-1156-Pla-thinner-4-oz/dp/B004GJBWVM

I don't know if they are the same but to me it would be logical to presume that they are.  Someone who is adept at 3D printing may be able to help sort this out.

Today’s chemistry lesson is what is PLA. Sorry for giving the same answer.  There will be a quiz later.  Further research leads me to believe in the 60’s it was just short for PLAstic enamel paint and simply branding.

"Pla", referring to Testor's enamel paints, has nothing to do with polylactic acid. Polylactic acid is a thermoplastic which is not a component of any type of paint.

The prices on that site are a bit  "ambitious".
