I don't have any experience with 22ple but I've seen CQ done and did opt gloss coat on mine. The OGC is the easiest to apply. With CQ there's also the extra step of putting reload on afterwards.
I used the CarPro foam block applicator and micro suede cloth. Just wipe it on in a cross hatch, and buff off with a microfiber towel. It flashes pretty slow. And the microfiber towel wipes off the high spots with extremely light pressure and one swipe. I did about a 2x3 foot section at a time. Not sure about the longevity, as that will vary greatly with care and maintenance afterwards, and OGC has not been out too long, but I believe their claim of 2 years. Also, it looks better than opticoat2.0 IMO. More glossy
Don't think u can go wrong with any of them, really. And in about 2 years you can try a different one.
