Abstract

Claims (20)

1. A method of coating and protecting a vehicle surface, the method comprising:

(a) rinsing the vehicle surface with water;

(b) washing the vehicle surface with a cleaning solution;

(c) removing the cleaning solution from the vehicle surface;

(d) spraying a detergent resistant, hydrophobic film forming, car polish onto the vehicle surface, the polish consisting essentially of:

i. an alkoxy aminofunctional dialkylpolysiloxane;

ii. a long chain silicone quaternary blend comprising a diquaternary polydimethylsiloxane;

iii. a carboxylic acid;

iv. a surfactant selected from the group consisting of nonionic surfactants, cationic surfactants, zwitterionic surfactants, and mixtures thereof;

v. water;

vi. a cosurfactant selected from the group consisting of propylene glycol methyl ether, dipropylene glycol methyl ether, tripropylene glycol methyl ether, propylene glycol n-propyl ether, propylene glycol n-butyl ether, diethylene glycol-ethyl ether, diethylene glycol methyl ether, ethylene glycol propyl ether, and triethylene glycol methyl ether, ethylene glycol n-butyl ether and mixtures thereof; and

vii. an optional additional ingredient; and thereafter

(e) spraying the vehicle surface with water; and

(f) air-drying the vehicle surface, wherein the polish is an aqueous solution.

2. The method of claim 1 , wherein the alkoxy aminofunctional dialkylpolysiloxane constitutes about 0.002% to about 20% by weight of the composition.

3. The method of claim 1 , wherein the long chain silicone quaternary blend constitutes about 0.002% to about 50% by weight of the composition.

4. The method of claim 1 , wherein the surfactant and the cosurfactant each constitute about 0.001% to about 20% by weight of the composition.

5. The method of claim 1 , wherein the long chain silicone quaternary blend further comprises a quaternary polydimethylsiloxane.

6. The method of claim 5 , wherein the long chain silicone quaternary blend further comprises a silicone fatty amino quaternary polydimethylsiloxane.

7. The method of claim 1 , wherein the optional additional ingredient is selected from the group consisting of carboxylic acids, anti-rust agents, hydrophobic agents, fragrances and dyes.
