Interior Painting

OK paint guys. I am trying to re-paint the interior pieces to my vette. The original color was Medium Saddle. I took a piece of the interior to the local paint shop and they shot it with their color gun. They have mixed up the paint and it is close. I did not get a lot of paint so I have to try to do this correct the first time.

Now, my question. I have to add some flattener/flex agent to the paint. The interior came originally with what I would call a "semi-gloss" and not gloss paint. I am using DuPont paint and I am getting some DuPont flattener/flex agent. How does a person mix that stuff? To get "semi-gloss" would a guy mix it 80/20; 70/30 or what? Has anyone done this before and how did you do it?

Thanks for any help.

Steve

I am moving this to Body/Exterior as that is where the painters live...With flattening agents a little dab will do you maybe just a 1/4 teaspoon per quart..Saying that I am not a DuPont user....And you will need to shoot a test section to see if you got it right..may take a few tries until you are happy..

Somebody may have a specific formula; but I usually used a touch-up gun for smaller stuff, mixing about half a capful to a gun of paint. Then spray a test piece. Compare with what your old parts looked like and vary from there. It will usually take a decent amount of flatting base to get to an interior sheen.

Most of my experience in this was using Martin-Senour paints. Others may be different.

Used it a couple of times. I go by the P-sheet, don't have it at hand right now. I'll look for it tonight. It will tell you how to mix it. I did a 68 shelby GT500 and the interrior was flat black. I first mixed up semi and it was two shiney. So I'd go with the flat. It came out looking like it was pure basecoat but with clear. Factory!

are you using the Dupont interior paint? If so you don't have to add anything in it...it is ready to spray. You just buy it in the different gloss levels . Also if you have alot of humidity like we do where I am at, it will affect the flatness of the finish. Over-here ,if we use the semigloss interior dupont paint it comes out different gloss levels depending on the humidity. Sometime it comes out flat instead of semigloss. JMO Tim

No it isn't DuPont interior stuff. I had the local parts store mix up a gun read color & shade (Saddle Interior). They used NASOR paint. It is a truck acrylic enamel. That was their choice, I had nothing to say about it. After it was all done, I noticed that the paint was going to come out in a gloss finish. I now have the necessary stuff to spray. I obtained a small portion of DuPont flattening agent and a small amount of flex agent. Should be OK if I mix it all correctly. Will only shoot the stuff when the humidity gets to the 60% or lower. Preferably 50 % if possible.

Thanks for the input though.

I know you have already bought your paint but an easier soloution is to buy the interior dye from Corvette America. available in quarts or aresol. it is a perfect match and has the correct sheen.

I agree that the information can be obtained by looking at the product data sheet. It will have mixing instructions on it. Plus the guys at the store you bought the paint from should be able to help out as well. If I remember some flattening agents are variable, the more you mix in the flatter it will be. Be sure the paint is strained as some flattening agents will leave white crystals that won't mix into the paint and will show up in the finish. You can get some paint sample spray out cards from your auto body supply store and do some variable spray out tests on them and use the mixture that most resembles the factory finish. Experiment and have fun!
