2. Not using
enough lubricant. You have to use enough
lubricant to actually lubricate the surface of your car.
If you're not using enough lubricant, you'll see clay
come off on the paint, and it's difficult to get that
clay to come off.
3. Putting too
much pressure on the claybar. You don't really
need any pressure on the claybar except the weight of
the clay itself. Just gliding it across the surface
lightly is enough to do the job.
4. Not wiping
off the lubricant quickly enough. It's best to do
small sections at a time and wipe off the lubricant
quickly when you're done.
claybar stuck to your fingers. As the heat from
your hands warms up the clay, it will get stuck to your
fingers, embedded under your fingernails, and so on. You
can avoid this by spraying your hands with the same
lubricant you're using for the car surface.
I used a
Griot's Garage. I've also had
good success with
Zaino's clay bar. I like to use Meguiar's speed
shine as the lubricant with the clay bar, mainly because
it has a nice cinnamon smell and the spray bottle
produces an unusually fine mist. Griot's Garage also has
a good speed shine product. Mother's and Meguiar's both
also make clay bar products, which are less expensive
and easy to find at places like Schuck's and Pep Boys,
whereas you have to order the Griot's Garage and Zaino
products online. Sal Zaino recommends using diluted car
shampoo, which is cheaper.
