REMOVAL OF CONTAMINATION/OVERSPRAY OF ASPHALT SEALERS/"SLURRY SEAL"

This time of year business are resealing their parking lots. Dependent on the mixture's viscosity, temperature, wind direction etc, vehicles in the area of the project may experience contamination by the sealers.

Asphalt requires an additional binder in order to seal and withstand the "dripping" of motor oil, transmission fluid, brake fluid gasoline and diesel fuel onto the surface.

This is due to the asphalt being a by-product of crude oil. The mentioned fluids are produced from crude oil and therefore attack the asphalt, dissolving it into a liquid.

The most common binder added to the asphalt is a furan polymer. It is a plastic derived from various alcohol's or furfural and ketone. The physical properties of furan make it resistant to solvents, most nonoxidizing acids and alkalis.

The attached procedure for removal has been tested on several vehicles and removes the contaminates without heavy rubbing which causes the asphalt particles to scratch the paint film.

The basic chemical reactions of the procedures is as follows.

1. The New Car Prep, due to the nature of its  
hydrocarbon structure dissolves the asphalt, the high pressure spray blows away the small rock or sediment particles from the vehicle's surface.

2. The application of the "A-B-C" system dissolves the furan polymer as well as any ferrous metals, which are normally present to some degree in the sealers.  Their presence is due to the sealers being a blend of various by-products obtained or stored in highly     industrialized areas.

3. The vehicles must be resealed as the process strips  all protective coatings from the vehicle, making it susceptible to I.F.O. O. and Acid Rain damage.

4. Goal - Remove contaminates from new urethane enamel paint vehicles without damaging paint film or paint resin system.

5. Procedure For Removal:

A. Vehicle must be cool - i.e. paint surface no more than 85 F.

B. Apply New Car Prep solvent to all painted surfaces and glass.

C. Pressure wash off New Car Prep.

D. Apply product "A" mixed 8 to 1 spray on - Do not mitt. Do not allow to dry on surface.

E. Rinse vehicle, remove excess water with water sprite.

F. Apply product "B" with soft applicator. Allow to  dwell 5 to 7 minutes - DO NOT ALLOW TO DRY.

G. Rinse off with pressure washer.

H. Apply product "C" mixed 128 to 1. Mitt entire vehicle.  Rinse

I. Dry with water sprite

J. Inspect vehicle for scratches.

K. Remove scratches with proper tool, pad and 
    product if required.

L. D.A. vehicle with paint seal. Allow to dry 15 to 20 minutes.

M. Apply Rubber protector to all tires, clean glass  while paint sealant is curing.

N. Remove paint sealant with orbital buffer.

O. Detail all areas of vehicle.

P. Inspect for quality control.

NOTE: Some vehicles may experience staining of flex agent parts. Procedures may not correct this and part may require refinishing.

Approximate vehicle time without vehicle power buffing - 2 1/2 hours.
