1. What is the difference between an orbital polisher and a rotary buffer?
Swirl marks are nothing more than micro marring in the paint surface. Under a microscope, they appear to be scratches; however, you can't feel these scratches with your fingers or finger nail.
Every time you wash or wipe down your car, you
create micro marring. The severity of the micro marring depends on your tools and the contaminants present.
The reason swirl marks and other micro marring show up so prominently on black and other dark colors is because the sides of the marring reflect light. When you polish, the edges are rounded and reduce reflection.
This diagram shows what severe micro marring might look like in a cross section of paint.
Here are the ten most frequent causes of micro marring (swirl marks):
with the incorrect pad or an untrained operator.
- Harsh polishing
compounds and paint cleaners.
- Towels and
applicators containing polyester threads.
- A dirty chamois or a
chamois that has not been properly maintained.
- Wiping down a dusty
or dirty car with a dry towel.
- A dirty car duster or
a car duster used on a car with too much dirt on the surface.
- Not keeping your wash
mitt or sponge properly rinsed.
- Automated car washes
with brushes and other wipers.
- Not rinsing your car
completely before washing, or not washing your car thoroughly
- Using a car cover
when the car or the cover is not clean.
The most noticeable areas for swirl marks
are the hood and trunk. On dark-colored
cars, they might also show up on the doors and fenders.
Bright colors do not show swirl marks as much because they
reflect more light. That doesn't mean they don't get swirl
marks; the marks just show up more readily on dark colors.
Black, of course, is the worst of all
colors for displaying swirls and other imperfections.
This picture, taken by Scott
Borders prior to detailing, clearly shows buffing marks and
other micro marring created by an inexperienced dealership
detailer with a buffer. No doubt the Ford truck looked
great when the owner took it home, because most buffer
jockeys use a high-gloss wax that temporarily fills the
buffing marks and other minor scratches.
After buffing and polishing, the swirl marks and hazing are no
longer visible, and the paint surface has a deep, wet look.
Scott did a great job, and the truck owner is very pleased.
2. How do you remove swirl marks?
Swirl marks are removed by polishing. Use a car polish designed for swirl removal, like Sonus Sonus SFX-2 Enhanced Swirl Remover. If your swirl marks are severe, we recommend using Sonus Restore (SFX-1) first to knock them down. Follow the application of SFX-1 with Sonus SFX-2 to restore full gloss. On the modern car finish, swirl remover polish must be applied with a machine, such as the Ultimate Detailing Machine. Modern paint is too hard to polish sucessfully by hand.
