OCW is much more user friendly than DP's Spray Sealant, apply and remove just like a QD. The DP product applies more like NXT Booster Spray. Spray, spread, let haze, wipe. You get the idea. Not hard to use, just not a total breeze like OCW.
Visually, OCW is more carnauba like, has a real deep glow while DP's has a more traditional sealant look. OCW is definitely a stand alone LSP, not 100% sure if the DP spray is meant as a stand alone or just a faster way to add layers over their traditionally applied Surface Shield.
I am looking forward to trying UPP's and Jeff's stuff. I'll go through the Acrylic Jett I have on hand before ordering the spray version but I'll probably get the Carnauba Jett much sooner.
