Update***
Initial application was done September of 2013. I used the paint, glass and wheel coating. In Minnesota and most of the upper Midwest for that matter, this has been the harshest winter in 30 years. So cold has it been that washing even in tunnel washes have to be timed with a brief warm spell, which seem to come far a few between. Here we are today, the end of February and the current temp at 1pm in the afternoon is -8 degrees.
What I have noticed when I do get a chance to wash is that beading on the hood and glass are still very evident and I mean "tight" beading. It's quite obvious that the Paint coating is still working at 5 months and counting quite well and have no doubts that it will last for quite a bit longer.
There is no doubt in my mind that for those of us that have limited or no chance at waxing during the winter months that this DP Paint coating is the cats meow for a long lasting durable finish. For those that want a product that takes a lickin but keeps on tickin. A "set it and forget it" if you will, it's a no-brainer.
