I can offer a bit of a more long term test on the Pinnacle Black Label Ceramic V2 Coating as well as their wheel coating. First I don't think there is a huge difference between any of the ceramic coating brands so I am not necessarily touting Pinnacle but I do like their entire line of products. I coated my new F150 Limited Black, my wife's Escape Black, my CVO Black, and my wife's Dyna a little over 6 mths ago. I used the Wheel Coating on rims, brake calibres, engine, and bike pipes/exhaust. The Wheel Coating has a high heat tolerance and has lasted without issue on the engine, pipe shielding and mufflers. Further there is no worries of this stuff going chalky on matte finish parts. I have removed my heat shields off the mufflers. Prior to this I was a nothing but high end wax with a sealant on top guy. Pinnacle Souveran Wax topped with Wolfgang Sealant.
First, ceramic coating has no correction properties what so ever, so what ever you are going over such as swirls left behind are going to be there after you coat it so make sure you go through all your correction steps.
Second, I found the ceramic did leave some streaking/shadows on black and I had to use some different angle light sources to ensure a consistent finish and look. I never seemed to have this issue with old wax and seal. Now with this said, it was more evident on the vehicles with large panels then on the bikes.
Third, I found the best results came by a next day follow-up with a coating of the booster. It aided in removing shadows and seemed to blend the job together.
Evaluation: Shine - I don't see the shine is any better or worse then just waxing and sealing. I personally did not find a next level deal with it.
Protection - This is where at this point I think the ceramic has excelled. Other then some follow-up with the spray detailer, this stuff has lasted and continues to protect months later. Manufacture says 2 years but verdict is still out on that. I have especially noticed this on the rims. Brake, belt dust, and road grime wash right off after application of some APC and hosing off. Ceramic does not appear to be affected by APC where I think APC's break down waxes and standard sealants.
Maintenance- I have not used a wash mitt on our bikes since applying the ceramic and thus preventing swirl marks on the finish. I first spray the fronts with 50/50 mix of Hydrogen Peroxide and water to break down bugs. Bugs and grime in my opinion fall off this stuff with very little help. I then foam canon a APC (I use Riccardo Kleenzit APC) on the entire bike and let it sit for just a few minutes then wash it off with low pressure nozzle on the pressure washer. Then blow dry that takes no time as water just does not stick to this stuff, and if you are real fussy like me, then give a quick wipe with a microfiber towel to remove any water spots. The coating will "not" prevent water spots.
Conclusion- I think the longevity of the Ceramic is better then a sealant. You would have to do your own cost analysis based on what you used to maintain your bike, but a small bottle of the coating, wheel and booster will last ages if you are only doing your bike. Does it shine better? Well this is a coating so it is going over the shine level you have already produced and protecting it. All your work goes into preparing the surface not putting the coating on!
