Made my wife’s Beamer shine like a diamond in a goat’s ass Definitely impressed with how easy it is to use this product. Goes on easy and buffs out with ease. Great value for the money. Would definitely recommend and I would buy again!

Money well spent I have tried tons of products and by far this has been the best ever, money well spent, very easy to apply, wait until it hazes and wipe off

It's ok-ish for this price I gave some time to review the product, I wanted to see how it would perform over about the month.First thing that I notice, that the water repellant quality isn't that great. I primarily was looking for water repellant. After 1 application, the water drops were consistently forming and there were a lot of water sheets on the windows(when droplets do not form). I did 2 more application (spread in time) and only after that it somewhat worked.It's hard for me to say how long it will last, it's been about the month and the main challenge for it is regular car washes, so far it holds.I covered the entire car, not just windows, I don't see much difference with the dirt, dust and water droplets.Overall for the same price there are more better solutions, even some of them will require longer application time (but it's worth it from my experience, since it lasted for almost 2 years. Doubt that this one will last as long, but I might be wrong here).TLDR: It's ok-ish for this price, may require multiple apllications to work.

A hard shell, and an easy sell! Applied a week ago (as 2 coats over 2 days) to my 20 year old Toyota. Easy to apply and quick to finish with a clean microfibre cloth, no buffing required. Half the bottle is left after 2 coats. The shine and depth of gloss is incredible, better than any other product I have used. A coworker commented on "how fresh" the paint looked. The surface is smooth and buttery. I replaced my wiper inserts after doing the car, and the surface was so slick that I almost slipped and fell while leaning against the front fender!A quick wash yesterday to remove some bird droppings (which came off with just hose pressure anyway) and the whole car was dry in about 10 minutes. Water does not want to be there. Morning dew became millions of tiny tiny beads rather than larger droplets. I applied it to all the glass too, however for the front windscreen, it did leave a faint haze that catches sunlight in a streak after using the wipers. Glass cleaner should remove any of that residue though.I have used "Testudines Wax" and "Megs" ceramic spray-on detailers, both were OK but only lasted for several weeks before they were noticably deteriorating, which put me off using them all over again. If you're going to be doing that every 2 months, you may as well stick to a regular wax.I would recommend this and would buy it again.

Unbelievable, shine and protection This stuff works amazing. It’s phenomenal. Water beats up like nobody’s business and beats up like crazy on my truck. Use it on the glass also the same results. Talk about a shame is unbelievable better than a new paint job. I will be back to get more.

Super shiney! Less noticeable dust. TBD how long it lasts and UV protection holds up Comes with gray cloth. Sprays with a grayish tint makes it easy to see where it lands. No scent which is great. Minivan paint color is Honda grayish white and clear coat looks super shiny! Cannot really tell if the paint itself is brighter or looking better. Did a double layer after letting 1st dry on the sunroof/top of windshield area, and hood. Also works well on the black trim around the windshield. Extra layer also at corners of van, door handles and bumpers. We live in dusty California and Constuction nearby is kicking up a ton of extra dust. While i can see some dust particles after touching the van i cannot tell by looking at it there is a dust layer, very little if any. Hoping to mostly protect clear coat from oxidation and feathering. Time will tell how long it lasts in hot dusty climate. Will update.

Great Stuff! Mrs. Approved I have put a couple other products on my 2022 BMW Black, it has always been clean and shiny, however this product gave it the extra touch to give car a glass/mirror shine. Very easy to apply and buff off. Overall can’t wait to apply second coat next weekend after washing it. Even the Mrs. said Wow! that looks Great!

    I applied a glass coating to my windshield and needed the surface to be perfectly oil-free. Windex wasn’t cutting it. This Prep Spray removed all the road film and old rain repellent instantly. My new glass coating bonded perfectly and has lasted through winter.

    Great product for stripping old wax. I could literally see the water behavior change from beading to flat sheeting after using this, which means the old protection is gone. My only gripe is the smell—it is VERY strong alcohol. Definitely use it outdoors or with the garage door open. But it works 5 stars.

    This is a heavy-duty cleaner. I bought a used Honda CR-V that had some dealer stickers on the back. I peeled them off, but the sticky residue remained. A few sprays of this Prep Spray and it melted the glue right off without harming the paint. A great bonus use!

    I used to mix my own isopropyl alcohol and water in a spray bottle, but I always worried about getting the ratio wrong and damaging my clear coat. This pre-mixed 75% formula gives me peace of mind. It feels safer, lubricates better while wiping, and strips the paint squeaky clean. I prepped my entire BMW M3 with it before ceramic coating. Flawless results.

The final clean before protection

The finish is won before the coating.

Polish oils, wax and invisible residue can weaken a coating before it ever cures. Prep Spray leaves a clean, bare surface so protection can bond evenly and last.

What shampoo alone leaves behind
A true residue reset

Remove the invisible layer.

A clean-looking panel can still carry polishing oil, wax and fingerprints. Prep Spray dissolves that film and lifts it into the towel—without haze or streaking.

Good prep, answered

Know before you wipe.

Use Prep Spray as the final cleaning step immediately before wax, sealant, ceramic or graphene protection.

When should I use Prep Spray?

Use it after washing, decontamination and polishing, once the surface is cool and dry. It should be your final wipe before protection.

Can I spray it directly onto the panel?

You can, but lightly misting a clean microfiber towel gives you better control and reduces overspray. Work in small sections.

Is it safe on glass, chrome, vinyl and PPF?

Yes, it is designed for exterior paint, wheels, glass, chrome, vinyl and paint-protection film. Always test an inconspicuous area first.

Should I use it in direct sunlight?

No. Work on a cool surface in the shade with good ventilation, and keep the product away from heat or flame.
