OP, just to be sure, did you already do paint correction on your truck? If not, this is your most important and probably costliest step (unless you do it yourself). If you have scratches and swirl marks, all the Opti-Coat will do is seal them in there semi-permanently. Unless you're really good at polishing and buffing paint (I don't know, you could be a professional auto detailer), I'd recommend Opti-Coat PRO and have the shop do full paint correction if you have a lot of swirl marks / light scratches.
Remember, paint correction prior to being coated is KEY. Unless you go through that step first, the OC is kinda pointless. OC doesn't really add any shine or gloss, it protects the paint underneath it. If the paint /clearcoat are swirled, you will still see them with OC. If you want it to look perfect, your original clearcoat nees to look perfect 1st.
Also, there is not a lot of "slickness" to OC. I still use OC spray wax or a quick detailer to add extra gloss and slickness. But even without a topper, the water beads like no ones business. I LOVE that.
Sorry, no pics yet. Had it for 3 months on my black express. I need to wash it again before I start taking pics.
