Caring for your car

Rear window cleaning

While the roadster's rear window has

the advantage of being extremely flexi-

ble, there is the disadvantage that it has

a relatively-soft surface. For this rea-

son, clean the rear window only with a

soft, antistatic cloth or with BMW Con-

vertible Rear Window Cleaner.

If you wash the vehicle frequently in

brush car washes, and in particular in

those with hard brushes, faint scratches

in the rear window may result. With the

window replacement system you can

replace a heavily scratched window at a

relatively low price. Please contact your

BMW center for additional information.

Do not use spot removers, paint

thinners, solvents, gasoline or

similar substances for removing spots

from the convertible top or from the

rear window. These materials destroy

the rubber seals, which will lead to

leaks. Use only BMW-approved clean-

ers.<

Exterior finish

To provide effective corrosion protec-

tion, multilayer paintwork is applied at

the factory. Cataphoretic immersion

priming techniques are supplemented

using special body-cavity protectants,

with the application of specially-devel-

oped and extensively tested materials.

A layer of flexible PVC is first applied

to the undercarriage. Following this, a

comprehensive undercoating treat-

ment with a wax-based protectant is

applied.

Regular maintenance makes an impor-

tant contribution to maintaining the

safety and value of your vehicle.

Increasing awareness of the effects of

harmful environmental factors on vehi-

cle finishes have led paint and vehicle

manufacturers to initiate programs de-

signed to further improve the durability

of their finishes. Despite this, environ-

mental factors which occur locally or

regionally can have negative effects on

the finish of your vehicle. These should

guide you in determining the frequency

and extent of your efforts to maintain

the vehicle finish.

Depending upon material and type

of impact (perforation of paint layer),

physical stresses from sand, road salt,

gravel, etc., can cause corrosion to

start extending beneath the finish, start-

ing at the point of impact.

Road dirt, tar spots, dead insects, ani-

mal droppings (strong alkali concentra-

tion) and tree excretions (resins and

pollen) all contain substances capable

of causing damage when allowed to

remain on the finish of your car for any

period of time (spots, etching, flaking,

separation in the top coat).

In industrial areas, deposits of flue dust,

lime, oily soot, precipitation containing

sulfur-dioxide (acid rain) and other envi-

ronmental pollutants will damage the

car's finish unless adequate care is pro-

vided – even though this is generally

limited to the outside horizontal sur-

faces.

In coastal regions, high levels of atmo-

spheric salt and humidity promote cor-

rosion.

In the tropics, in addition to ultra-violet

radiation and high humidity, tempera-

tures over 105 7 (40 6) in the shade

are common. Under those conditions,

light paints can reach temperatures up

to 175 7 (80 6) and dark paints up to

250 7 (120 6).
