Review: Life Changing Stuff - Let me first say, this is incredible stuff and priced amazingly, don't have second thoughts on purchasing it. For background, I'm a professional detailer with a small business, I have detailed well over 200 cars and tried hundreds of products on the market. I was hired to wash, clay, and wax a Newmar 45' motorhome. I knew it was a MUST to find something easy to apply but still provides great protection, I would never recommend spray wax for long term protection. I came upon this stuff and it was advertised to do exactly what I needed. I purchased 6 bottles (only ended up using a single bottle for this 45' long by 14' tall monster. So it goes a really long way. My biggest concern was ease of application and removal, a lot of products I use on normal cars would have taken years to apply to this job. I can very happily say that this was the best tool for the job, and an absolute must have for cars or motorhomes. This works great on regular automotive paint as its a carnuba based wax. I was able to apply it by hand to very large areas and then simply 1 wipe buffs it off once it has flashed on. The work time is great and you could let it sit for hours on the paint before you buff it off and itd still be fine. Made this job a breeze, not to mention it brings out DEEP gloss and reflection and has great hyrdophobic properties. I highly recommend this product and plan to use on my own vehicles.
Review: What a shine - It easily puts a beautiful deep shine that lasts all year. Simple to use, much better and easier to apply then paste waxes. I wax two vehicles , a midnight blue pickup and an urban grey suv. Different colors with the same outstanding results.

### ⭐⭐⭐⭐⭐ What a shine
*by T***T on December 11, 2025*

It easily puts a beautiful deep shine that lasts all year. Simple to use, much better and easier to apply then paste waxes. I wax two vehicles , a midnight blue pickup and an urban grey suv. Different colors with the same outstanding results.

### ⭐⭐⭐⭐ Works for an easy protection, does not clean much
*by E***S on August 24, 2022*

Despite being advertised as a cleaner wax, this did very little cleaning. For water marks, etc, I had to use my auto Mother's cleaner/wax. However this product went one easy and buffed off easy. I think it is good for use between more significant wax jobs (which I do 1-2 per year in my RV).
