Overall I'd say pretty well. A few of you have asked me to post some pics so here are some I took with my iPhone. I'll add some higher res pics as time allows. In general some of the gloss or sheen is gone, but that is to be expected. In the approx. 3 years I have had it on my truck I have put it through an auto car wash probably 10-15 times and washed it by hand ONCE. The reason I did this was I wanted VERY low maintainence and it has been exactly that. If I had it to do over again I'd do it the same. Durabak sells a product called "Rejuvinator" that will bring back the new sheen but I have yet to use it even though I've had some for a couple years. I'd call the current color dark asphalt if I had to describe it and I like it quite well!
