FAQ
Common questions about Hydro-Barrier.
What is a SiO₂ rinse aid?
A liquid you spray onto wet paint just before the final rinse. The SiO₂ carriers bond to the paint, leaving a thin ceramic layer that beads water and sheets it off cleanly.
Will it strip my Quartz Ceramic Wax?
No — it layers over it. Use Hydro-Barrier weekly to top up your Quartz protection between full applications.
How much do I need?
A light mist per panel is plenty. Dilute 1:10 in a pump sprayer for the most economical use.
How long does the beading last?
2–3 weeks per application. Reapply at every wash to keep protection topped up.
Is it safe on glass and trim?
Yes — you’ll get hydrophobic windscreens and slick rubber seals as a bonus.
