paint extra p rotection, particularly if water no
longer beads on the clean paint.
P rotec t plastic body parts with ca r wax in the
same way as the vehicle body.
During warm weather dead insects tend to
collect on the front bumper and on the for­
ward area of the hood. They are much easier
to remove from paint that is waxed
often.
Poli shing
Polish your vehicle only if the paint has lost its
shine and the gloss cannot be brought back
with wax.
If the polish used does not contain preserva­
tive compounds, the paint must be waxed af­
terwards.
