It doesn't have a smell which is nice for those who are sensetive to smell. Sometimes I think that it can leave some vinyl too fake looking... Like tire covers.
I felt that ONR did not provide good lubication and light cleaning abilities were not that great. It also could not cut through some bugs on the mirrors. I did mix it as suggested on the bottle with distilled water. I do love ONR for rinseless car washes, it works fantastic.
Crystal Mist no...
Mine manual says the same thing and to stay away from cleaners and conditioners that contain wax. I use warm water and a microfibre towel and wipe them down monthly, after vacuuming the seats. The conditioner I use is SAAB branded, since my car is a SAAB. Seems to do well...
Tire Shine, I like Pinnacle Blck Onyx. P21S is about as good as you are going to get, plus its safe. I personally like Poorboys Super Slick and Shine car wash, but that is an opinion, I have used the DP stuff and prefer the PBs.
