Have you tried the Ultima Waterless Wash Plus? I'm wondering how it compares. I've been happy with it but my only other real comparison besides the OTS brands is the ONR diluted for QD purposes.
Collinite has the flip top cap option now to eliminate any issue with caps not tightening but I'm not sure if all the new bottles come with it or not since I haven't bought any lately.
I've been mainly a lurker here as I'm not really into hardcore detailing like some of you but I recently had a very positive experience that I wanted to share.
I would consider myself a casual detailer mainly just interested in protecting my paint. My main arsenal consists of Collinite...
