Autobase Plus, and it is good stuff.
1956 Mercury, Heath Green. I can't remember the code, but the jobber I buy from couldn't find a formula in his system. They scanned and matched it. Perfect match too.
I used Glasurit on the last Heath Green car we did. I won't even mention
that price. Suffice to say ridiculous doesn't even begin to describe it.
I was primarily an ICI painter for 12 of the last 15 years, Been to the school, shadowed the rep on his route, took a lot of Qs from other shops, blah, blah, blah. I know ICI/NEXA inside out. It's the cat's ass.
That being said, the 30 or 40 times I've used
any Sikkens or Akzo Nobel paint, I've been impressed. I used the old AutoCryl on a Cascar stocker for a couple years, and it was so versatile and user-friendly, if I hadn't been a "Certified NEXA Refinisher" that paint alone would have been reason enough to seriously consider changing paint lines. The bottom line would have been the big deterant.
Autobase is just as good, if not better. I did a Black 67 LeMans for a guy in Warren, Michigan, and it was one of my best spray jobs ever.
Your rep is right - Sikkens has much more tech support than Lesonal, and that is part of the reason for the higher price. The rest of the reason is better quality (read: higher cost) materials. The same goes for any paint line, from any manufacturer. Ever get someone in your shop yet, bitching about warranty on Lesonal? If you haven't yet, you will. Just laugh at them and tell 'em they shoulda bought the good stuff.

Dupont? the best I can say about Dupont is it sprays beautifully, looks like velvet when applied, and covers like water. $$$$$$$$$$. Add to that the fact that the local Napa store is the only retailer here and you now know why it's been years since I've bought any. Sprayed it several times in the last couple years. Bought it, no.
I just dug into the business price list (the first time since '08 I've looked at it) and the last US quart of base I mixed was December 2007, GM Black 8555, and it cost me $71.42.
Far cry from $117.
Like I say, I near shit when he told me the price.
The Omni, well yeah, you're right. I've had good luck with it, but it's not very good compared to U-Tech. I think PPG uses a lot more fillers in their lower lines than anyone else. Even the lowely Nason works better than Omni.
Do you get to go the painter's tech classes when you retail, or do they have a separate jobber class? One of my buddies works at a CQ store and took a couple painter classes instead of the counter-guy classes they wanted to teach him. He says he has new respect for us painters.

Almost forgot - waterborne is going over well here. July is the final production date and December, I think, is the final sale date for the "banished" solvent products. Still quite a few un-converted shops and you can't find a paint rep nowadays if your life depended on it, but I think by December, most will be on board.
I've used Autowave a bit, Aquabase, and Sherwin-Williams (can't remeber the name of it tho'). The colour match and lay-down are fantastic and the hype about BIG changes in shops are a bit overblown. Cleanliness, tho' is absolutely critical.
