We have been using Dupont Cromax Pro Waterborne paint Here at Moultrie Technical College for about a year with great results , awsome color match easy to instruct with . It has good coverage and is easily blended.
We've been using Standox Standohyde for about two years with no problems. Yes, we get the occasional color match issue that you would get with any paint water or solvent. No warranty issues, no complaints from my painter, increased productivity, and an increase in materials profit. My only regret is not doing it even sooner.
P.S. DuPont, you can email me for the address to send the check to!
