Engineered to bond to paint, glass, wheels and trim, it creates a slick, hydrophobic, UV-resistant protective layer that lasts up to 12 months between applications.\u003c\/p\u003e\n\u003cp\u003eWhere polymer sealants and waxes give you weeks of protection, Defender SiO2 builds a real silicon dioxide layer that resists chemical contamination, makes maintenance washes faster and keeps paint feeling glass-smooth. Apply over cleaned paint in 30 minutes. Apply over an existing ceramic coating to extend its life and refresh hydrophobic behavior.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Detailers Trust Defender SiO2\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReal SiO2 chemistry:\u003c\/strong\u003e not a polymer sealant.

Defender SiO2 is a thinner, sprayable version of the same chemistry, lasting up to 12 months. It is the same active ingredient at a more accessible price and easier application.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs Defender SiO2 better than wax or polymer sealant?\u003c\/strong\u003e\u003cbr\u003e\nYes, in terms of durability and chemical resistance. Wax lasts 2 to 3 months and is removed by alkaline cleaners. Polymer sealants like Bead Maker last 8 to 12 weeks. Defender SiO2 lasts up to 12 months and resists chemical degradation from acid rain, bird droppings and harsh detergents.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use Defender SiO2 over my existing professional ceramic coating?\u003c\/strong\u003e\u003cbr\u003e\nYes, this is one of its primary use cases. Apply every 3 to 6 months as a topper to refresh hydrophobic behavior and extend the life of the underlying coating.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I prepare paint for maximum Defender durability?\u003c\/strong\u003e\u003cbr\u003e\nWash thoroughly, decontaminate with Iron Buster, clay bar any remaining bonded contamination, then wipe down with an alcohol-based panel prep. This creates a chemically clean surface for the SiO2 to bond to the clear coat.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill Defender SiO2 enhance gloss on dark paint?\u003c\/strong\u003e\u003cbr\u003e\nYes. The SiO2 layer creates a glass-smooth surface that amplifies depth and reflectivity, especially noticeable on dark colors. Pair with proper paint correction for maximum gloss.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow often should I top up Defender on a maintenance schedule?\u003c\/strong\u003e\u003cbr\u003e\nFor a vehicle in daily use, every 2 to 3 months keeps hydrophobic behavior at peak levels. For a garage-kept weekend car, every 4 to 6 months is plenty.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhere is P\u0026amp;S made?\u003c\/strong\u003e\u003cbr\u003e\nP\u0026amp;S Detail Products is manufactured in the USA by Appearance Technology Group (ATG).
