The only difference between the Ex and Pro line are the base coats in the the actual kits. The Ex kit is really a case enough for 10 cars, versus the Pro which is enough for two cars or two coats.. The Ex base coat is a bit more durable with a higher composition of Fluorine & glass fibers. A warranty comes with the Ex as a professional detailer must apply it. It's a program for detailers to provide a higher end service by adding a warranty that the distributor covers in case of loss of gloss or protection. That's about it...
