The Sonax Polymer Net Shield is an aerosol based spray on sealant! Net Shield is formulated using organic and inorganic hybrid polymers that once sprayed, immediately react to oxygen and cross-link on your paint. The surface tension created causes water to bead up and roll off, allowing your vehicle to stay cleaner longer. The polymers produce a crisp, clear reflection while protecting your paint from UV rays, acid rain, bird droppings, airborne contamination, road salt and more. Simply spray Net Shied onto your paint or a foam applicator pad, spread evenly and buff off any excess. Your paint will be protected for up to six months in only minutes. If you are looking for a quick and easy way to protect your paint, give the Sonax Polymer Net Shield a try!
