SiO₂ spray coating · 8 oz / 16 oz
Nexgen Ceramic Spray
The highest SiO₂ concentration we found in any spray-on coating, and it shows: the deepest wet-look gloss of the test and water that still sheeted cleanly months later. You get it in minutes with a towel — no buffing gear, no cure time — which is the whole point of a spray. It's the rare bottle that beats far more expensive products on the panel and at the register.
Highs
- 13% SiO₂ — among the most concentrated DIY sprays made
- Deepest, wettest gloss in the field
- Spray-on, wipe-off in minutes; zero cure time
Lows
- Wants a clean, cool panel and a dry towel to finish streak-free
Verdict The most gloss and the most protection per spray we tested. Our top pick.
