Abstract
Abstract Disclosed is a paint sealant and method of applying the same to painted surfaces wherein a T.F.E. Teflon in a dispersion carrier is mixed with a fine abrasive in a dispersion carrier and heat is applied by buffing to burn off the dispersion carriers so as to produce a durable protective coating of Teflon. A second hard coating is applied to cover the Teflon.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
71 words
A process for protecting a painted surface, which comprises: providing a paint sealant composition in the form of a tetrafluoroethylene monomer, a tetrafluoroethylene dispersion carrier, an abrasive compound and an abrasive dispersion carrier; buffing the paint sealant composition on the painted surface until sufficient heat is created to dissipate the dispersion carriers and to polymerize the tetrafluoroethylene monomer, so as to create a layer of a polymer over the painted surface.
Claim 2
Dependent Claim
71 words

Claim 3
Dependent Claim
28 words
In the process of claim 1, coating the polymer layer with a hard protective coating from a group of polishes consisting of waxes, silicones, acrylic resins and plastics.
Claim 4
Dependent Claim
47 words
In the process of claim 2, the step of buffing the paint sealant compositions including buffing until a high gloss appears on the paint, continuing to buff the paint sealant compositions after the high gloss appears so as to allow the abrasive compound to generate sufficient heat.
Claim 5
Dependent Claim
27 words
In the process of claim 3, buffing the paint sealant composition with a wool pile pad rotating at a rate of 1500 to 3000 rotations per minute.
Claim 6
Dependent Claim
43 words
In the process of claim 2, providing a silicone polymer and a dispersion carrier therefor in the paint sealant composition, buffing the silicone polymer dispersion simultaneously with the tetrafluoroethylene monomer and abrasive dispersions to create a coating of silicone over the polymer coating.
Claim 7
Dependent Claim
21 words
In the process of claim 2, buffing the paint sealant composition to temperatures ranging from 270 degrees to 300 degrees Fahrenheit.
