WHAT IS RUBBER?
The first rubber material used for every sort of rubber product
was natural rubber. Natural rubber comes from the rubber trees in
South America and Asia. Years ago, natural rubber was used to make
tires and weatherstripping. The first rubber tires were actually white,
but researchers added carbon black to make tires stronger. Today's
automotive rubber is usually made from a synthetic formulation known
as EPDM.
METRO rubber is made from an advanced, propriety EPDM formula
which has superior ozone and UV resistance. METRO's rubber products
are also molded using high heat and 40-to-125 tons of pressure,
which gives them a longer life and clean, smooth looks.
METRO's parts quality, and look and feel usually surpasses the
quality of the original rubber parts. All the fine details of
the original parts are precisely duplicated, even the details
that won't show after installation. The most advanced materials
combined with the latest technologies make METRO rubber the highest
quality rubber parts available.

MAINTAINING RUBBER
To give your rubber that clean new, jet black look, start by
cleaning it with mild soap and water. Follow with a protectant (Armorall)
or even a silicone-based furniture polish (e.g. Lemon Pledge). Do
not spray protectants directly on the rubber. Rather, apply it to
a damp rag then wipe it on.
Some rubber will naturally bleed paraffin, which will look like
hardened candle wax. Use a solvent to carefully remove any visible
paraffin.
RUBBER ENEMIES
Rubber contains plasticizers that eventually "evaporate"
from rubber, leaving it hardened and cracked. This is a naturally
occurring process, but heat, sunlight, smog, chemicals and gasoline/oil
can shorten the life of rubber parts.

TYPES OF RUBBER
There are two basic types of rubber used today in cars and trucks.
Dense rubber is harder and used for gas and brake pads, hood bumpers
etc.
Cellular sponge rubber is used for weatherstripping, to seal doors,
trunks, hoods and roofs. Sponge rubber varies in degree of softness
from one manufacturer to the other. The greater the softness, the
better. Softer rubber does a better job filling in the tiny cracks
and bumps along surfaces it presses against. This prevents water
leakage. Softer weatherstripping also makes it easier to close doors,
trunks and tailgates.
METRO's SUPERSoft sponge rubber is the softest and most durable
auto rubber you can buy. SUPERsoft has a unique closed micro-cell
structure. This cell structure helps give SUPERsoft its superior
softness. The material formula and secret manufacturing process
gives SUPERsoft better shape "memory", better looks, and
better durability and resistance to abrasion, tearing and ripping.
Unlike other auto weatherstripping, SUPERsoft does not absorb water
-- a key condition to completely sealing out water.
