Rick, you should REEEALY try this out. It’s 50% cheaper at Eshine, than NXT is on Canadian tire, and it will definalty outlast it. If you don’t like the look, you can easily top it with my devil-brew of the most kickassestness spray wax… on black, it’ll be wickedly reflective. (I would still use Souveran though)
Check out some of the ‘Click n Brags’ on autopia using #16… can’t argue with the results! You’ll get 2-3 months at most with NXT, #16 is deep into the 5-6 months range with the most perfect water beads ever. (Well, second to the sealant that I use) 
Good luck!
