They are expensive, but damn are they worth it. I sprayed a hood a few weeks back. Da'd it down with 1200 then 1500/2000 by hand and then the trizacs. About 20 min of sanding and 20 min of polishing done!!

Here was outcome!

No problem, So correct me if Im wrong...you still hand sand/block it with 1500 and 2000 grit then hit it with a DA palm sander with trizacs 3000 then buff? Hood looks killer.

I only 1500 and 2000 by hand because I didn't have and of those grits on a hook it disc. The initial 1200 was with a da. This is just a race car hood. I will always hard block by hand, But the trizac 3000 with a da cut my polishing time in half!
 
Pretty much done except badges and a final clean and polish before he picks it up in March. To much snow for him to drive it home. I've got to hand it to some of the guys here on the board, your work is outstanding. I have another one in the shop to start. This one came all the way from MN. Long way to come for a paint job...must have been the good price since he was quoted $15,000.00 for the same thing I'm doing. Pictures to come soon on another trend. Thanks everyone. Merry Christmas!IMAG0408.jpg

Looks beautiful.. I would be proud of that anyday!

OrangeJuiced.. If it was DBU or DBC 9700 ( ppgs pre mixed basic black ) it should mix 1:1... Its been a long time since I used any of that. I guess since I found SPI around 7 years ago or so, but would only think it still mixes the same..

Now if we can get Barry to make the black base again, i can finally use the last half gallon i have.. Im holding onto it and refusing to part with it until he makes more lol!!!

Thanks, Yes it's DMD1683 Deltron Base coat Black tint. (DBC) and i used SPI reducer 1:1. It's black....paid $220.00 out the door for it per gal.
 
Car looks great. Nice job!

I shot some DBC 9300 (same as 9700) Black this past fall and my supplier instructed me to reduce it at 2:1. The PPG tech line backed it up when I called them to verify. Just on black basecoat: 1:1 on all other colors. They said a possible adhesion problem for black at 1:1. Please understand that I am not trying to rain on anyones parade but just passing along information that was given to me. Remember they said "possible" and not "likely" so I would not worry about it since it is done and looks great. It will most likely live a sheltered life anyways.

Thanks for the info. So i called our PPG paint rep and he said who ever you talked to must not know what they are really talking about. He said if that was the case they would have changed it on the mixing ratio on the cans, and/or recalled all the product out there. I sometimes don't believe everything i hear from any of those guys. Who really knows. I've done any adhiesion test just to make sure, and everything seem fine. But thanks for the heads up.
Maybe BerryK will chime in on this one.
 
Correct me if I am wrong because it has been a long time since I have used this line, but from what I remember 9300 was the DBU reactive base, and the 9700 was DBC.
That could be part of the confusion??

It could also be that the shop I worked at had DBU9300 and DBC9700??
 
Chad again off of memory, I only used DBU when I started using bc/cc.. I thought I remembered that it always mixed 1:1.. Of course this from my memory, but dont ever remember it mixing 2:1?? Maybe Im wrong here, but I feel sure Im right lol.. Im going to bed lol

9300 seems to be the SS concept black
 
I should have said 1:1/2 but 2:1 sounds easier to pour!

At the time I was using both the DCC single stage Concept and the DBC basecoat. Both were available as 9300 or 9700. Supplier said they were the same but I started with 9300 so I just stayed with 9300 throughout the job.

The DBC basecoat can labels do not have a mixing ratio printed on them, just the tech sheet page number (P-175). The DCC single stage can labels do have the mixing ratios printed on them and the tech sheet page number (P-168).
 
I've always mixed all DBC colors 1:1, never knew about the 2:1 recomendation for black but i think I know why. Blacks always tend to flash off fast but they hold solvent-something to do with the pigment and problems with solvent going through. I would bet there are a lot of painters out there that like to spray black wet (like me) and if flash times were unknowingly rushed, application was heavy, and clear was applied to soon I bet there's a great chance for delamination. And I bet that's why they recomend less reducer in the black-it's the only thing I can think of...
 
Just a heads-up for anyone not familiar with PPG, the DBU and the DBC are two different basecoat systems. DBU uses a reactive reducer ; DBC uses a regular urethane reducer. I do not know the mixing ratio for black in DBU as I only use DBC.
