Cadillac 2007 - Manual (Page 505)

Tires
To clean the tires, use a stiff brush with tire
cleaner.
Notice: Using petroleum-based tire dressing
products on your vehicle may damage the
paint finish and/or tires. When applying a tire
dressing, always wipe off any overspray
from all painted surfaces on your vehicle.
Sheet Metal Damage
If the vehicle is damaged and requires sheet metal
repair or replacement, make sure the body
repair shop applies anti-corrosion material to parts
repaired or replaced to restore corrosion
protection.
Original manufacturer replacement parts will
provide the corrosion protection while maintaining
the warranty.
Finish Damage
Any stone chips, fractures or deep scratches in
the finish should be repaired right away. Bare
metal will corrode quickly and may develop into
major repair expense.
Minor chips and scratches can be repaired with
touch-up materials available from your GM dealer.
Larger areas of finish damage can be corrected
in your GM dealer’s body and paint shop.
