Nice, I think you'll love the sliders, I know I do mine. I had CBI powdercoat mine because Nathan gave me a deal on it. Before I decided to have them powdercoated I was going to just rattle can them. I decided against the textured finish for touch up reasons, not knowing how the paint would go over the bedliner. So, sorry I can't really answer the question since I had the same concerns.
Wish I had made the meetup, I'm sure it was a blast. I have run Peters Mill and Taskers Gap a few times, but would really like to check out some of the trails south, like Dictum Ridge. Gotta get another meet together.
P.S.: be prepared for a pita install on the driver side slider. When it comes time shoot me a pm, I have a couple tips.
