Recoating Procedure
CAUTION : To avoid serious personal injury when ap-
plying any two–part component paint system, follow
the specific precautions provided by the paint
manufacturer. Failure to follow these precautions
may cause lung irritation and an allergic respiratory
reaction.
1. Clean the surface.
2. Soak the wheel with Amchem Alumi Prep No. 33 or
equivalent for 1 to 3 minutes. Rinse the wheel with
water and blow it dry.
3. Soak the wheel with Amchem Alodine No. 1001 or
equivalent for 1 to 3 minutes. Rinse the wheel with
water and blow it dry.
4. Finish with Ditzler Delclear Urethane and Ditzler
Ultra–Urethane Additive or equivalent, using three
coats.
1st coat – spray on a light mist coat; let dry.
2nd coat – spray or paint on a light coat; let dry.
3rd coat – spray or paint on a heavy double wet
coat; let dry.
5. Let the urethane dry for 24 hours or flash for 30
minutes and force dry at 60°C (140°F) for 30 min-
utes. Allow the urethane to cool for 5 minutes be-
fore mounting the wheel on the vehicle.
OFF–VEHICLE BALANCING
Perform wheel balancing with an electronic off–vehicle ba-
lancer. The balancer is easy to use and gives both a static
and a dynamic balance. Unlike on–vehicle balancing, the
off–vehicle balancer does not correct for drum or rotor im-
balance. This drawback is overcome by its accuracy (usu-
ally to within 1/8 ounce). Secure the wheel on the balancer
with a cone through the back side of the centerhole, not
through the wheel bolt holes.
CORRECTING NON–UNIFORM TIRES
There are two ways to correct properly balanced tires
which still vibrate. One method uses an automatic ma-
chine which loads the tire and buffs small amounts of rub-
ber from high spots on the outer two tread rows. Correction
by this method is usually permanent and, if it is done prop-
erly, does not significantly affect the appearance or the
tread life of the tire. Tire truing with a blade–type machine
is not recommended because it substantially reduces the
tread life and often does not correct the problem perma-
nently.
Another method is to dismount the tire and rotate it 180 de-
grees on the rim. Do this only on the tire and wheel assem-
blies which are known to be causing a vibration because
this method is just as likely to cause good assemblies to
vibrate.
