Have a 69 442 I am restoring, eastwood has a landau black and a satin black, which would be the proper one to use? Thanks

 

It's mostly Landau black you should use. That's semi gloss, but the look varies depending on the humidity + weather. Use that on like seat backs, headrests, arm rests, steering column, etc. Some things are 0 gloss, like the dashboard top. Go to Autocolor library and there is a chart for what's painted whichever color.
