I'm trying to touch up the interior of my 64. The black around the glove box and other places on the dash are starting to ware off as they do with old cars. Does anyone know what kind of black paint (flat, gloss, satin) is used and where I can get some?

 

PPG has the factory OEM interior color codes just like paint codes.
They come in one of two different materials depending on what your using them on. the 1st is a low grade 2K urethane paint. It's a single stage, 2-part paint that has a flatting agent to correctly match your interior codes.
It can be used on any metal, fiberglass or hard plastic surface. The urethane can be used to change colors as well.

The 2nd type is a dye not a paint. It sprays with a normal spray gun and mixes like paint but it is a dye. It is used for vinyl, carpets soft dash pads etc. It can NOT be used to change color, only refresh the color. Ive never used the dye because I don't like the idea of it. It is water borne and comes ready to spray. My logic says anything that would need a dye, just just be replaced.

But for the hard interior surfaces the interior grade PPG can't be beat.
It is about $200 a quart so make sure you need it first. If you have a very std color interior such as black, then I would just buy some low gloss 2k urethane paint. Eastwood, and TCPglobal both sell a flat black and a satin black that works amazing for interior trim. I used the TCPglobal satin black on my 94 shifter and radio bezel and it turned out to be a stronger and better looking finish then the OEM dulso crap.
Eastwood and TCPglobal are not your only options. ANY automotive paint store can mix you a low gloss 2k urethane paint for around $80 a quart. (depending on brand). If you can give me your year,make, model and what color the interior is I can get your interior paint code from my PPG colormatch program.

Here is a pic of my bezels painted with the 2K urethane.

 

I bet the OP owns a 1964 Chevrolet Corvette and his interior color is BLACK... whatcha think?

 

Well I figured it being a 64 he might want the correct shade/gloss of black. Purest are usually picky. their is a different code for black interior and black trim. I don't know if his full interior is black or if it is the accent color.
And believe it or not their are many shades of black. The C4 alone has three different black interior codes
