- ^^^^^^^^^^^^^^^^^DON'T DO THIS !!! Never use a rubbing compound on a
- clearcoat painted surface! This will not only remove the stain, but the
- clearcoat as well! A rubbing compound is VERY abrasive and will scratch
- a clearcoated surface.
-
- When I 'detail' a car with a stain such as this, one that has been
- on the surface for a while, I use a pre-wax cleaner that is meant to
- be used on clearcoats. If that does not work I then try Tar&Bug remover.
- this has the chemicals neccessary and should do the job. Clearcoated
- surfaces must be treated differently than an otherwise normal paint.
-
- Think of a clearcoat this way :
-
- surface
- CLEARCOAT layer 1
- CLEARCOAT " " 2
- CLEARCOAT " " 3
- CLEARCOAT " " 4
- CLEARCOAT " " 5
- COLOR " " 6
- COLOR " " 7
- sheet metal
-
- Note: traditional paint is not compatible with clearcoat
-

-
- Rule of thumb for protecting the surface of your car should be wash
- it twice a month with carwash such a Raindance liquid. Never use
- dishwashing liquid! Dishwashing liquid removes the oils from within the
- paint and causes permenant damage short of repainting the whole car.
- Also, you should wax the car every two months depending on the severity
- of the weather. If you've had two-three heavy rainstorms, most of the
- wax is gone. I recommend a well known wax such as Simoniz liquid wax.
- Try to avoid thick liquid waxes as they are harder to remove.
-
- good luck !
