Claying is a process that is new to the world of automotive detailing and
has found enthusiastic acceptance. It's not hard to understand why, as its
resume reads like a miracle cure, and after reading it you may think that
it's too good to be true. But claying delivers.
The clay we are talking about is similar to the toy "Play-doh" that
kids enjoy although a special type is required for car detailing. It
performs it's function by removing the contaminants from the surface of
the paint. It works by virtue of its flexibility as it easily forms the
exact contour of the surface it is in contact with. What it does for a
painted surface is similar to the function of polish, but unlike polish,
clay is not an abrasive. This is an advantage for the beginning or casual
detailer, as no harm can be done to the paint. Claying also does not
remove wax, so unlike polish, there is no need to reapply it after an
application. It works on surfaces that might not be appropriate for
polish, such as glass, brightwork and trim items. Claying is also
relatively quick and easy when compared to a polish job. Clearly a winning
situation all around!
To work with clay you will need a lubricant. Fortunately what you use is
not critical and many products will work fine. Many clay kits ship with a
"Quick Detailer" spray which works. Frankly water will work in a pinch.
Our recipe consists of a tablespoon of car wash detergent in about 20 oz.
of distilled water and dispensed using a spray bottle. Others have
reported that Windex and other glass cleaners work well.
Some Experimenting The "baggie test" is the way to go and is recommended
as an easy way to demonstrate the power of claying. Put your hand in a
ordinary sandwich baggie (the thin kind, not the thick rugged ones) and
spray a test area of the paint with the above described clay lubricant.
Then go over the paint surface with just enough pressure to get a
feel for the surface. You'll detect all sorts of bumps and defects, many
more than are apparent with even a close visual inspection. Claying is
done after the car is washed, but before it is waxed, assuming that you
are planning on a wax job. To use the clay, apply some of the clay
lubricant to the area you are going to work on, which shouldn't be larger
than about 2' x 2'. Then glide (in other words, use only minimal pressure)
the clay over the surface. If the lubricant is working the effort to move
the clay over the surface will be next to nothing; you are really guiding
it's movement more than anything else. A lot depends on how much the clay
has to pick up. This will also work on paint overspray and environmental
overspray.
As you progress, you'll note that the clay bar gets thinner.
You'll then have to rework the bar so that it is thick again by kneading
it. Some detailers like to just fold it over, the reasoning is that it
will have a cleaner surface. You'll get a feel for how it is working by
the way it glides over the paint surface. This "feel" will also tell you
when the clay bar is losing its effectiveness (it's resistance increases)
and needs to be replaced. When you are finished with a section, dry it
using the same towels you use after you wash the car. It's a good idea to
rinse the entire car with a hose after you are finished with the claying
task. When you are finished, do the "baggie test" again. The results will
be easily felt.
Claying is an odd process. If you haven't tried it, it is can be
difficult to understand as it doesn't seem to conform to most of what we
know about car detailing. If this is your thinking, we encourage you to
give it a try. It really is easy! Many amateur detailers are a bit wary of
the concept but after they try it, they are sold big time.
A clay bar is good for about four to five treatments. This depends on
factors such as the size of the vehicles and how dirty they are. One
important note: if you ever drop a clay bar, you MUST throw it away. The
potential for causing scratches from material it picks up is just too
great. If you intend to reuse the clay bar, store it in a box or baggie to
keep it clean and so it won't dry out.
