I bought a bottle of it years ago. I think I used it once. I'm not saying it isn't good. But I had 3 products to try at the time, including Wizards Mist-N-Shine and Duragloss 951.
I ended up liking the Duragloss the most, followed by the Wizards.
Unfortunately, the only one that survived the freezing garage temps was the Wizards. Seriously, bring your products inside and don't let them freeze or they will separate and be ruined.
Fast forward to today: these were polymer-based gloss and slickness enhancers, things we call "quick detailers" or "drying aids" today. They only last until the next wash. There are much better products if you want something more durable. You've no doubt seen all the ceramic spray sealants everywhere.
