    69 interior - paint or dye?

    working on the black interior of my 69 L46 convertible. Have to replace a few pieces - parking brake console, windshield vinyl trim. Remaining vinyl/hard plastic parts are in good shape but things like dash pad and others could use fresh color. And I want to try to keep the same sheen/color for all interior vinyl/plastic parts.

    Sem makes a paint product called Color Coat that has a good reputation (they have 3 black colors-Landau, Gloss and Satin. In aerosol or qt cans). A friend of mine used it on his '66 442 almost 20 years ago and it still looks great. But I see the regular corvette vendors selling dye in spray cans and other references to dye on this forum. What's your opinion on paint or dye, and which brand/product is best to use?

    Thanks folks.

      This topic drives me crazy. YOU CANNOT DYE VINYL. What people call "dye" is actually elastomeric PAINT. I've been told on other forums that I confuse people by saying that.
      Well, if everyone called it what is, you wouldn't have to ask. BTW, not ranting on you, just venting in general.

      If you want call SEM and ask if it is actually dye. The color coat is what is wrongly called dye.

        I take it that you agree with me that the CA dye is actually lacquer paint.

            Re: 69 interior - paint or dye?

            As the OP asked, should Landau, Gloss, or Satin be purchased from SEM ?

            BTW, Richard, I have an '69 L46 that I'm trying to finish up, and I need some interior paint......elastomeric, I suppose.

            Thanks for posting the question.

              Hi Richard. I have one more metal dash part to paint and then I am on to the vinyl and plastic bits which is why I asked the question. MyL46 is a convertible, 4 speed with side pipes, cortez silver, all numbers matching. Restoring it for NCRS judging before putting it on the road. After the interior is done, all that's left to do is the glass, top and the myriad of loose ends that will be inevitable. Hoping to get the engine running again next month. Keep in touch with your progress.

              If the "dye" being offered by the corvette vendors is really an elastomeric lacquer paint then my angst as to what product to use decreases. Why would they call it a dye in the first place? Marketing pukes? I couldn't understand how dye could penetrate the surface of plastic/vinyl enough to change the color.

              The bigger problem for me then is getting the right finish/sheen to the parts. I was hoping to get some tips on what is the accepted best. This forum has been wonderful for eliminating a lot of costly mistakes for any issue that comes up. Of course that doesn't stop me from screwing things up on my own.....

              Absent any more suggestions here, I think I will pick up the black gloss and landau color coat and test it on a part that I am replacing. That tach/speedo portion of the vinyl is probably my best bet to compare finishes since it looks pretty good and probably has the least amount of sun damage to it.

                And if you use the SEM materials they offer a material specific primer

                  I guess I should provide so info since I opened my big mouth.

                  I'm not familiar with sheen levels from SEM. Sorry. I would go to auto body supplier and inquire.

                  I was fortunate to purchase a supply of saddle interior color coat made by Dupont. That's who supplied GM for the original coloring. Unfortunately that has gone bye bye.

                  If you search" auto color library "you will find the original specs for both exterior and interior colors, as well as what sheen level went on what interior part. Will at least give you some place to start.

                  You're fortunate that you have the only color GM made after all others ran out. Black.

                    update: I spoke to SEM tech support, nice guy David Anderson, regarding vinyl and plastic painting and color match. He said the Landau black was made in the 70's generally for vinyl roofs, but it had been a good seller through now. The prep isn't that bad - cleaning with soap (I used SEM soap), then following with vinyl prep sovent for vinyl. For plastic there are two steps after cleaning before paint - a plastic prep solvent then an adhesion promoter before paint. There is a different prep for ABS/PVC plastic. No priming required. All of this is on their tech sheets on their web site.

                    Anyhow, i painted a piece that is being replaced - half with gloss black, the other half with landau black. My wife and I compared it to a portion of the vinyl on the tach/speedo dash that had been tucked along the side by the center gauge cluster where it had seen no sun or wear. We both agree the Landau black is a great match. So that is what I am going to use on the vinyl. SEM says you could top coat with one of their clears to get a different sheen than what they already provide, but I see no reason to fuss with that.

                      Richard, Thanks for the update, maybe post some photos of some of your painted parts.

                        Rich,
                        Thank you very much for the thread. I just bought interior rear quarter panels for my 70 convertible, and they need to be painted. This thread is extremely helpful.
                        Thanks,
                        Allen

                          I'd like to see a pic of this test too. I'm going to want to re-black some of my '72's console parts and would like to see how the landau compares to the gloss SEM.

                            I used the original center upper windshield molding to conduct this test since I was replacing it with a new part anyhow. I prepared per the SEM instructions and painted one half with the Landau Black, the other with the Gloss.

                            This picture compares the edge of the tach/speedo panel that was unaffected by sunlight etc, with landau black Color Coat made be SEM

                            The next picture is the same Speedo panel with Gloss Black Color Coat by SEM.

                            I know pictures can not come through as well as looking at the parts directly. And I am no photographer. But I thought the Landau was the better match and went with that. I am happy with how they turned out.

                              Thank you for posting the pics. I agree the Landau looks to be a good match.
