Silicon Based Sealants
Silicone based products are easy to apply, have a significant depth of shine and are more durable and longer lasting than waxes.
Silicone polishes have some advantages but they also demonstrate serious problems, particularly when a vehicle requires painting.
Molecules from silicone polish will undergo a process called “drifting” or “drift” causing the silicone to embed into the painted surfaces and penetrate into the pores of the paint. This silicone penetration into the paint causes severe problems during repainting or touch up process.
Whenever the paint is washed by water, it will literally cause the silicone to embed further (drift) into the paint. The silicone will continue to drift down through the pores in the paint and then into the vehicle’s metal. Over time the silicone will continue to embed into the paint on a vehicle, thereby exposing the surface to the elements just like conventional car waxes, composed of Carnauba wax, when they melt (due to summer heat) or during a regular car wash.
Once silicones have permeated the paint, the primer and the metal, paint will not properly bond to the metal. Because there is no mechanism to prevent drifting, the silicone will eventually drift all the way to the base metal, thereby effectively ruining the vehicle’s exterior. Therefore many car manufacturers void the paint warranty if silicon based products have been applied to a vehicle.
