The
Paint Perfect Alloy Wheel Repair Process
Our 18
point full refurbishment service is the best way to restore your
alloy wheels to factory finish and give a long lasting and durable
finish. This method is also ideal for enhancing the appearance of
your vehicle by changing the colour of the alloys.
The
vehicle is brought into one of our secure, alarmed workshops and put
on axle stands. The wheels are then removed.
The
inflated tyres are checked for leaks and bulges in the sidewall.
The
centre caps and spigot rings are removed, inspected for damage and
stored.
The
tyre is then removed and checked for wear, foreign objects and
damage.
The
valve and weights are then removed.
The
wheels are checked for buckles and flat spots. These can be repaired
on our hydraulic wheel straightening rig.
The
wheels are then immersed in a chemical bath to remove paint, powder
coat, brake dust and corrosion. This process can vary in time
depending on the coating on the wheels. In some cases this can take
up to six hours. The chemical bath is the best way to get the wheels
back to bare aluminium as media blasting can be too aggressive and
leave a pitted surface. Blasters that are recycling their media and
using the same equipment for aluminium and steel can also impregnate
the wheel with tiny pieces of steel. This cross contamination can
accelerate corrosion in the wheel.
Once
removed from the tank the wheels are then neutralised in a water
bath and jet washed clean.
Once
dried the wheels are inspected for cracks and other damage that
would require TIG welding.
The
wheels are then hand sanded to remove kerb damage and other
imperfections in the surface.
Etch
primer is then applied inside and out followed by high build primer.
After
the primer has been cured on a bake cycle it is sanded down by hand
ready for paint.
Base
coat is then applied inside and out followed by 2K high solids
solvent clear coat and then cured on a bake cycle.
Once
fully dry new valves are fitted and then the tyres are put back on
the rims and inflated to manufacturer's recommended pressure.
Spigot
rings are refitted where appropriate and each wheel is balanced.
The
wheels are refitted to the vehicle and torqued to manufacturers
specification. We do not fit wheel bolts using an impact gun as this
can over tighten and stress the bolts leading to failure. It also
can cause damage to locking wheel nuts.
We
refit the centre caps and lower the car off the axle stands.
The
vehicle is then given a complementary wash & mini valet.
We have
seen wheel “refurbishments” where the tyre is left on the wheel,
in some cases the wheel is not even removed from the vehicle! This
approach can lead to a number of problems including;
Poor
adhesion – Without the tyre being removed the wheel cannot be
keyed properly and the new paint starts to peel off from the edges.
Excessive
film thickness – The more paint build up there is on the wheel the
more prone it is to chipping.
Pressure
loss – If the tyre is left fitted the inside of the wheel cannot
be inspected and treated. Corrosion forming between the wheel and
tyre bead is a common cause of pressure loss.
Reactions
– We have seen paint finishes with reactions from over painting a
previously refurbished wheel or silicone reactions from tyre
dressing.
Saving a
small amount of money in the short term will be a false economy in
the long run.
