Rain-X PRO 620179 Graphene Exterior Detailer Spray, 16oz - Graphene Shield Technology Gently Removes Light Contaminants and Dirt, Enhances Gloss and Shine

So, disclaimer, I don't use this on glass regularly. I haven't found anything that works well on glass besides invisible glass aerosol. And it's okay on trim. There are better products that do those things... same reason I don't use 3 in 1 body wash. You do not need to use a lot. If you have a car bigger than a sedan, obviously you will. Paint wise? Wow. I've used many different spray detailers, quick detailers, you name it, anywhere from $10-30 a bottle. This stuff is the most resilient I've used, and is NOT a replacement for actually ceramic or graphene coating your car. Obviously your mileage will vary depending on how thoroughly you wash and how often you use your car... I thoroughly go over every inch of my car every time I wash it. On my last wash, it had been about a month which is the longest I will ever go in between. Car was sitting through some snowstorms, drove through a good amount of road salt and sand, the typical New England experience. I brought it to the self-service car wash that I always do (soak, power washer and/or hand wash is a must) after this long, and I couldn't even get the water to stay on the car. My car is nearing 6 years old and the paint isn't perfect from the previous owner, but wow. Easily a month or longer this will keep your car GLEAMING and anything will come off with a quick rinse or just a wipe. The paint is literally a mirror, for quite a long time, not like a quick-shine product which has impossibly high shine for 2 days and it's gone. I hate to say it but I would pay much more than they charge for this product to get the same results.

On one of the bottles the spray neck was smashed in and some product leaked out

takes some extra buffing to remove.

I am living in an apartment so I do rinseless wash at a parking lot outside. I was struggling to find a proper way to wash my car outside and products. I found that the following way and this product were working great with me. 1. Rinceless wash panel by panel (using McKee's N-914) to avoid drying and any water spots 2. After mostly drying of a panel with a drying towel (using Rag company's one), apply this Rein-X graphene detailer panel by panel. (Tips: I applied a couple of sprays to only a small part of a panel. This helped avoid any nasty residues/spots. Spraying out a wide area may cause forgetting to wipe them off, and they dry out with nasty spots). This way, I found no streaking and no residues. The gloss and slickness were just excellent! I love the quality and price of this product. And would recommend it to novices of car detailing, like me! Very easy to use.

Rain x stopped making the two in one car detailed. I ran out. I’m sure this last and looks good. Just know it’s not as easy to remove as the two in one detailer. Reason being it seem a bit greasy. However with enough clean rags and elbow grease it’s fine. The two in one detailer I used on the glass also which worked as good as original glad rain x. I would be a bit hesitant to use this on glass. Maybe being greasy or oily makes it last longer.

I haven't washed or waxed my car in years. It's 14 years old. I bought this spray on an Amazon special just for kicks. I'm glad I did! This thing works! I washed my car first because it was covered in dirt and bird poop. Then I sprayed this on and wiped it off and WOW! It's shiny, the water beads up and rolls off. My car looks amazing now! I love this stuff!

this to your car. I had washed and dried the car thoroughly before starting to apply this finish product. Take your time, with small sections. Apply the product, wipe it clean and buff it before moving to another section. I used a ten inch buffer when the full body was done and it looks like a professional job. I've used rain-X products before and have always been happy with the results. Excellent!

Best finished I have bought. Beats wax. I have not washed the car in long time. I spray this on and wipe off the dirt. Love this.

Very good quality. Happy with the purchase.
