Description

404 Maintenance System Bundle

The 404 Maintenance System combines 404 Detailer and 404 Topcoat into a complete maintenance and performance restoration package engineered to preserve gloss, hydrophobic behavior, surface slickness, and UV protection between major coating applications.

Designed to work together, this bundle provides both routine surface maintenance and hydrophobic performance restoration for coated and uncoated vehicles alike.

Included In This Bundle

404 Detailer

A multi-purpose maintenance spray engineered to safely clean light contamination, enhance gloss, add UV protection, and maintain hydrophobic performance without masking or overriding the surface underneath.

404 Topcoat

A dedicated hydrophobic restoration and sealant spray engineered to reinforce and restore water behavior, slickness, and surface performance as protection naturally declines over time.

How They Work Together

404 Detailer maintains the surface through regular upkeep, contamination removal, gloss enhancement, and UV protection.

404 Topcoat restores and reinforces hydrophobic performance while extending surface behavior and protection longevity.

Together, they form a complete maintenance cycle designed to keep surfaces cleaner, glossier, and performing at their best.

    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.

    Definitely a high end application

    Definitely a high end application, ease of use, especially the removal, which I was thinking would be more difficult considering it cured for 30 minutes, but it was not a problem. Would definitely purchase again.

    Hydro Silk Car Wax is INCREDIBLE

    I finally tried Hydro Silk and I’m officially obsessed. This stuff is next level. For anyone familiar with old hard waxes that are a full workout, this is a breeze! Wipes on easily and the paint pops when you wipe it off like nothing I’ve seen before. It’s ridiculously easy, lasts for months, and gives crazy shine. Even my neighbor asked where I got it detailed. If you want that auto show ready look without spending hundreds, get this. Seriously, best results I’ve seen in years!

The proof

Real coats. Real beads.
Real owners.

  5. Incredible product. Blown away by the depth of gloss after one application. Genuinely the slickest finish I’ve ever felt on my paint.

  6. 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.

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.
