How Automotive Paint Is Mixed – Acura Project


– [Cameraman] ‘Kay, if
you’re looking for the paint code location on a ’91 Acura Integra, if you’ll go to the driver’s door, that’s the left front door, you’ll see your vehicle
information right there. It’s not on that, but if you look up on the pillar, right above your striker, you’ll see where it says color, and this one happens to be BG-22M. ‘Kay, now we got the paint code, and we can go to the
computer mixing system. We’re using the PPG mixing system, and I go in and pull it up, and now you can see that it pulls up the system, and I wanna hit search, and then I’m gonna hit standard. Now, you put in the paint code from the factory, the OEM code, which was BG-22, and then I hit continue, and that pulls up the color
that we’re looking for, and you can see it up there, highlighted. So, I hit continue, and you see there’s some variances. Now, this is still set on Deltron solvent, so I’m gonna need to change
that to the Envirobase. So, we’re shooting this in waterborne, and whenever I do that, you can see there’s only a prime. So, in waterborne, there’s
no variances for this, and that makes it convenient. Many times, there’s variances. Now, you can see there’s
a red line on the bottom, and that’s because that weak white T402, there’s too little of that to mix that small of an amount. Six ounces is the
smallest amount I can mix in this specific color. So, now, I’ve sped it up a little bit, get through this, and I put the cup on there, and it doesn’t really matter,
the weight of the cup, ’cause that balances out
whenever you hit start. So, I get the first toner, and you can see it’s a -76.7. Well, we want to take
that all the way to zero, and we’ll go through the toners as it gives us that, in order, and you can see that’ll get zero. You get to 0.4, you wanna drip it in at this point, ’cause that’s not much. I usually try to get it to zero. You can see that one’s zero, so I hit next, and notice that it resets. Now it’s at -68.4, so the next color that I’m putting in asks for this many parts. So, I apply that, you know, pour that in, and this is the way
colors for cars are made. I know it’s a little different than you may see at Sherwin-Williams, or at Walmart house paint. It’s a little different setup, but each color, depending on the color, it may have anywhere from three to 10 different toners in it. It looks like I’m really
shaking that hard. I’m not, just ’cause it’s in fast-forward, but this does not have a stirring, a agitating system,
because it’s waterborne. So, you just wanna give
it a couple gentle shakes. If you shake it too hard, you’re gonna put air bubbles in it, and that’ll ruin the paint. Also, notice how I’m holding, with the left hand, the bottom, and I’m using the right hand to go over and pull the trigger. That gives me more control. I found this to work good when trying to be accurate, ’cause this has to be accurate. If you’re two or three parts over, the color may not match the way it should. You also notice I get down to the .4 or .5’s, .2. It’s just dripping in. I mean, one drip can make a difference. So, I hit zero, hit the next one. You can see there’s very
little to this, 1.2. That is not much, but it takes that little bit of color to make this certain color. It looks like I’m shaking it really hard, I’m really not. I’m gonna pour this one in really slow, because that’s not much. If you over-pour, you may have to remeasure, and it makes a lot more paint you need, and it’s just a waste of paint. Now, here’s that .4, this is the one that kept red-lining. .4’s not much paint. I’m gonna allow it to drip in until I get it to zero. I was able to get all these to zero, 100% accuracy. Usually, if I’m plus or minus one point, I’ll go ahead and go with that. Now, we need to reduce it, and it’s gonna use the weight in the cup, and we’ll leave it on there. Now, it tells you how much reducer. We’re gonna reduce this 30% with waterborne reducer, and you see that’s gonna
take 39.9 parts of this. Now, this you have to
be very careful with, ’cause it pours out fast, but if it does over-pour slightly, it’s not gonna change the color. It’s just gonna change
the reduction of it. See that, I did go over, .2. I’m gonna just go with that. Well, it moved down to .1. So, anyway, that is how
you mix automotive paint. Hope you enjoyed this tutorial. Thanks for watching, and we’ll talk to you in the next video.
