Been detailing my cars for over 15 years and I've never heard of Rubbit. After checking it out, I agree that it looks like a typical "waterless" wash product, albeit with a twist by using a foam sprayer. So, here's my two cents:
1. Waterless car wash products are great IF used within their intended application. Like others have said earlier, they are great for maintaining an already generally clean car. This means that the car only has minor water spots (not the ones that have etched through the clear coat, but ones that have developed from a recent rain shower), dust, minor road grim, etc. In other words, if it's been weeks since a car wash, or the car has clear clumps of mud, thick grime that you can easily accumulate on your finger, etc. using this product will scratch, mar and damage your clear coat. So, if Rubbit is like Optimum No-Rinse Wash ("ONR" in the community; essentially the OG of such products), it would be a great tool for keeping a clean car looking its best on a week to week basis.
2. Generally my BS meter goes off when a product is heavily advertised on YouTube. Such advertising campaigns are not cheap and you have to question why a new company, ostensibly without a large budget, would devote a large portion of their costs on advertising. There are tons of highly reputable rinseless car wash products from companies that are well respected in the car detailing community that have been on the market and used by professionals for years. I'd go that route instead. Rubbit seems like a product that doesn't really do anything new other than package already existing components (towels, sprayer, solution) into a marketable product to lay people.
3. I too have all my cars PPF'd and ceramic coated. Even as a detailer, you're going to get minor swirls and scratches from time to time. It's simple physics - every time you touch your car with a microfiber, wash mitt, dry towel, etc. there's going to be particles being dragged against the surface of your car. Our cars live in the real world, not computer chip clean rooms. It's going to get scratched, end of story. All you can do is minimize this by using quality products and good technique. I say all of this because even well maintained cars will need a yearly polish to get rid of such damage, especially if they're daily drivers. So, don't sweat it too much, is my philosophy. If you already know your car will be lightly polished on a yearly basis, you won't obsess over minor nonsense like...
4. On a similar point, I wouldn't put too much thought into Ph balanced car washes. Like a lot of hobbies, car detailers know that there's no shortage of businesses that are all too happy to create a problem out of thin air to sell you something new and trendy. We've seen it countless times. A quality ceramic coating has already been engineered with the average car washing experience in mind. Companies like Rubbit are simply trying to play on your obsession with your car to scare you into believing that your expensive coating will melt away in your average touchless car wash after a few visits. While it's true that coatings do diminish with time and car washes, I'm highly skeptical that using Ph balanced car washes would make any kind of material difference. Thankfully, every coating I've ever heard of has a supplemental product that can be sprayed on and wiped off every 6 months or so. You use it as needed and it's generally as easy to work with as a quick detailer.
5. You can accomplish what Rubbit appears to do with already existing products, most of which have a proven track record. I too live in an area of the country where dragging out the pressure washer, foam cannon, and buckets is not feasible in the winter. So, I simply run my car through the local touchless car wash to knock off the big debris, park the car in the garage, assess the remaining grim, and go from there. That usually looks like using the tried and true waterless wash method which consists of spraying the car with plenty of product to loosen remaining grim, filling a 5 gallon bucket halfway with warm water and the correct amount of product, soaking about 15 high quality microfiber towels in the solution, then gently wiping the grim off the car, making sure to use a new towel frequently. Easy peasy.
. Best I’ve seen. Sorry,
