i start my new job as a painter on monday at a shop that uses dupont chroma base, any tips or suggestions about how to use this stuff

Depends. Is it Chroma-base, or Chroma-premiere??? The premiere covers better. They spray about the same. Easy to use and forgiving, but I've seen more problems with it lifting old sub-par substrates more than I did when using PPG stuff. If it's something you think you're gonna have problems with it lifting, spray it on a little drier, and use 7175 or 7185 basemaker instead of 7160. I've been spraying mostly PPG stuff lately, so I don't know if they've improved the DuPont stuff lately. I did like the way it dries flat, it can be nib sanded with 600 grit in spots to take out small nibs.

Overall, it's easy to spray and user friendly. :yes:

x2 on what Dave said. I've found it to be extremely easy to use and have not had any issues with it on the cars I've shot, but, I've only been doing restoration/overall refinishes starting with bare metal. Just make sure you don't use a slow reducer in the base and a fast activator with the clear. I've always used the 7175 Mid Temp reducer with the base as a slow (high temp) reducer with the clear.

I used it on a couple cars we have done just to try it and I like the PPG system a lot more. The coverage isnt that great seemed to use more material.

x2 on the slow reducer for clear. I used mid temp (70-80 deg) and had to shoot it below 70 to get it to flow out. No flow out = orange peel.

I used to work at a Buick dealer that used PPG and the higher ups made us switch to Dupont. We all complained and threatend to quit, but once we started using it our productivity went up and the jobs looked better with less effort. I can honestly say in 12 years using Dupont products I have NEVER had a paint failure or issue with their product. I strictly use Dupont chroma-premier products on the nicer jobs.
