bought two Zep Commercial Professional Sprayers. $4 on amazon as an addon item. Bought two of them and they have been great for making detailers with ONR (blue) and ONRWW (green). i generally find a lit parking lot at night and use microfibers and these filled bottles to wash my car and avoid car washes.
i am going through the regular blue ONR much faster just because of all the bird poop/pee I deal with on a daily basis. I think it is still king when it comes to utility. The ONRWW does smell great, you definitely smell the carnauba wax. I'd imagine this stuff is similar to Meguiar's quick detailer. Been using it almost like a spray wax, after doing ONR W&S first.
