Protect. Restore. Maintain.

Three bottles, one chemistry.

Hydro Silk lays the foundation. Topcoat refreshes the hydrophobics. Detailer keeps the finish clean between sessions.

Protection cycle

Most protect once.
Then fade.

Wax burns off in weeks. Generic sprays mask shine without bonding. Most ceramic coatings need a full strip and reapply when they fade, assuming you can tell they faded at all. The 404 system runs on a different model.

  • Non-permanent, by design.

    Wears off cleanly. Never strips your paint.

  • Top up, don’t restart.

    Refresh the beading every 3 to 6 months without redoing the prep.

  • Built to layer.

    Three bottles, one siloxane chemistry. Each role supports the next.

  • No re-buy treadmill.

    Maintain the system for years, not weeks.

The do-it-all set

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.

Using the system

Three layers, one chemistry.

This isn’t three random products. It’s one siloxane chemistry, applied in three roles: foundation, refresh, maintenance.

  1. Apply.

    Lay down Hydro Silk. Wipe on, walk away. Wax-level gloss, SiO₂ hardness, hot-panel safe.

  2. Maintain.

    Wipe with Detailer between sessions to keep dust, fingerprints, and UV off. Supports the chemistry underneath instead of masking it.

  3. Restore.

    Re-bead with Topcoat when water sheets instead of beading. Single-bottle revival, no full strip.

  4. Repeat.

    Cycle the system over time. The chemistry maintains itself for years, not weeks. No re-buy treadmill.

Start with Hydro Silk.

The foundation of the system. 20% SiO₂, wax-level gloss, hot-panel safe. Everything else is built to extend it.
