Ok, I know at one time Barry explained to me why it seemed black single stage paint and base coat clear coat took longer to dry , to buff, but I don't remember the reason. It had something to do with the make up of the black paint. Can anyone (Or Barry) explain this in detail. Another painter also asked me about it, but I could not explain it exactly. Pigments in the black color? Doesn't it basically take like close to double of most other colors to dry before buffing without lots of swirl marks? Hopefully Barry sees this and can give a nice answer too!
 
Dark Green, Dark Blue and of course Black, any of these colors with a lot of black carbon makes the paint dry totally different.
The carbon used is very temperamental and with its polarity tends to fight the solvents from escaping, that is one of the reasons you can take a perfect black black base coat and using a crap reducer or a fast reducer end up with a brown or gray cast next to another black car.

So sensitive, I had a batch of black base made about two months ago and it was spraying perfect but I had never used this carbon before and to 2800 lbs I added 3lbs of a black dispersion agent blended nice and slow for 30 minutes and when i sprayed it, it looked like a black red pearl.
$6000 into the waste tank because the polarity was wrong for that carbon.
 
Wish I could have got some of that black red pearl. Thinking about painting my car black with red stripes but the red I have is to bright. Maybe it would have worked with what you had mixed up.
 
Guys the red cast black would not work.
The blacker the black the finer the carbon is ground and what happened in this case was my stupidity, since I was playing with a new source of carbon, fist I did not need to add more dispersant witch I have used many time in black as this one is made for only use in black but I was adding a little for preventing future settling.
The reaction was, it cause all the carbon to clump together and so it would be a transparent black.

One employee has used for some suspension parts and if not in sun, you cannot tell it is not black and we gave a few gallons to an industrial plant.
Rest as of last week is on its way to the cement manufacturing company in Sumter, SC to be used as fuel.

Yes as a matter of fact I paid $200 per 55 gallon drum for them to take it and use as free fuel to make their cement to sell for $120 a yard.
Have you EVER meant a nicer guy???
