Best product I tried so far! My car looked fantastic after application of the coat. And plus points for their excellent customer support. I needed some guidance for after application and they were able to give me a good insight of what could possibly happeened and gave me options on how to address and fix those. I’ll definitely repurchase and try the other products they offer.

Seems good.
Just applied this to my wifes 2019 QX80. We purchased it used last year with 13000 miles on it andIwas toldthatit had been previously ceramic coated. The roof is wrapped in black ,so with 404 claiming it to be good for wraps I thought I'd give it a shot.A little does go a long way. It seems almost greasy when applying it, and you have to apply moderate even pressure to get it to spread. I was thinking as I applied it that I hoped it was not difficult to remove. It took about 45 minutes to apply a thin layer to everything but the actual roof so by thenwith I was within the suggested 30minute dwell time. The product removed pretty easily with the nice quality microfiber included in thepackage. Has a great shine, now to see how it holds up over time.

“Sure looks nice and clean with Chemical 404 taking the paint to a whole new level of shine!”
“Hydro Silk for the win! Thank you for keeping the Grom in the best shape from all the dust, pollen, bugs and more. The one and only for your protection!”

“I gave Big Panda a bath and hit it with that Chemical 404 Hydro Silk.”
“Incredible product. Blown away by the depth of gloss after one application. Genuinely the slickest finish I’ve ever felt on my paint.”
“As a professional detailer for 25+ years, I must say this product is top tier!!! The ease of application to the removal, and best part — you get absolutely no fingerprints left once applied. Even my high-end ceramic gets oily fingerprints.”
The do-it-all set
Get the trio
Three bottles, one complete system. Hydro Silk lays down the deep glow and razor-sharp gloss. Topcoat refreshes the hydrophobic layer as it wears. Detailer keeps the finish clean, slick, and UV-armored between sessions.
