I have a billit silver Honda and have used AIO/SG with great success. A few weeks ago I did my semi-annual cleaning/polishing and used Jett (second generation) over AIO. It came with a sprayer and that is the way I used it. Very easy and I have heard the new "Trigger" is even easier. After the AIO I did three coats of Jett all within a 24 hour period (SG recommends 12-24 hour cure time between coats) so that saves time as well. Plus, it is more convienant since you should keep the vehicle in the garage and not drive it on the road between your coats of sealant. Basically, I used Jett as I would a QD. It was not as easy as a QD but pretty close. It looks really good but on silver I would not say it is any better than SG, just easier. Now we will determine if the durability is as good. If so I will go with Jett from now on.
The probelm with determining "durability" (I'm still not sure how to define it) is that I am constantly putting stuff over the lsp. I've already used Acrylic Gloss, Menzerna's HGAS, Wolfgang's Spritz, FK425 and a couple other toppers/QDs and enhancers. In fact, I could not wait until the weekend and just used Duragloss AW - and it looks terrific. So with all these toppers on it constantly I don't know how the Jett is doing under it all. But I don't care really. I know I have a good, quality sealant in Jett (also SG) and all the other products clean and shine the truck just fine and some actually add a little sealant with every application. In fact, I probably would never have to use AIO and any sealant again as long as I keep putting on all this other stuff on a regular basis.
