One of the most common restoration questions that we get at Eckler's Late Great Chevy deals with the paint formulas for the 1958-1964 dashes and interior metal items. Quite a lot of information has been published about exterior paints. The codes and formulas have been deciphered and published for every color Chevrolet used during those years.

Unfortunately, the interior paints are not as easy to figure out as the exterior colors. To my knowledge, the only information that GM published on the interior paints was printed in the Chevrolet Service News fairly early in the model year. (For example, the 1959 interior paint numbers came out in the October, 1958 issue.) In the Service News, the formula numbers were published for the following paints: DuPont Lucite (acrylic lacquer,)DuPont Duca (lacquer,)DuPont Dulux (enamelj, R-MI Rinshed - Mason (standard lacquer) and Ditzler (lacquer).

The Service News did not specify the interior color to be used with a specific exterior color or a specific interior trim number. As a result it is sometimes difficult to know exactly what color to use. This is a good reason to note the color of the dash and any painted metal in the interior when disassembling a car. That is also why it is so important to study the truly unrestored cars that you ever come across. When you are taking your car apart, look for pieces that might have some original paint. You can sometimes find some paint on the back side or on an end of a garnish molding that is tucked under another piece. Using these to help match up with the paint number and formula will help.

Most of the interior paints used on the 1958s were exterior body colors. All of the 1958 interior paints were gloss, like previous years. In the 1959s there were some changes For the first time, Chevrolet used paints that were not exterior colors and the dashes, along with other interior metal parts were semi­-gloss or flat(Chevrolet refers to them as "flat," but really the paint was semi-gloss in today's terms.)

It appears that the interior (metal paints remained semi-gloss for the 1959-1961 models In the 1962-1964 models, the dashes and some of the interior metal pieces were sem-gloss,but other interior metal items were painted gloss. (Unfortunately, Chevrolet never (to my knowledge) published information which specified which items were semi-gloss and which were gloss.)

In this month's article is published the information from the Chevrolet Service News. In most cases, the paint numbers are given for the three most commonly used manufacturers of automotive paint. This information should really help those who are restoring back to original.

1958 Interior Paints
It appears that most of the interior paints were exterior body colors. Whatever paint was used, it was gloss.

1959 Interior Paints
The interior paints were different than exterior paints. This year, the paints were semi-gloss. Chevrolet said, "add flattening compound DUCO 4528."

1960 Interior Paints
Just like the 1959s, the interior paints were different than the exterior paints and again were semi-gloss. Chevrolet stated, "add DuPont 4828 "Duco" Lacquer Flattening Compound or equivalent."

1961 Interior Paints
Just like the previous two years, the interior paints were different from the exterior paints. Again, the interior paints were semi-gloss. Chevrolet stated in the October 1960 Service News, "To reduce gloss, add DuPont 4528 "Duco" Lacquer Flattening Compound or equivalent.

1962 Interior Paints
There were some changes in the 1962 interior paints. It appears that some of the metal items were painted gloss and some were painted semi-gloss. The dashes were still semi-gloss.

1963 Interior Paints
By this model year, Chevrolet had given specific paint numbers for gloss and semi-gloss where possible. Again in 1963, the dashes and some interior metal pieces were semi-gloss while other metal items were gloss. Chevrolet stated, "some Dupont and Rinshed-Mason (R-M) paints come only in gloss and flattener must be added".

1964 Interior Paints
As in the 1963s, Chevrolet had specific paint numbers for gloss and semi-gloss interior paints. The dashes were still semi-gloss as well as some other interior metal items. Again, some interior metal parts were painted gloss. Chevrolet stated, "Where low gloss is required, add flattening compound in accordance with label directions".
