You must have experienced this mostly during the mornings. Your car windows are covered with moisture. What do you do ? Take a piece of cloth and start wiping the windows, but the mositure returns !!!
When the temperature inside is warmer than the temperature outside, this can cause the water molecules to go through a process called condensation. Moisture is everywhere, even in a car that is just sitting. And because of interior items such as carpets, seats and other cloth or vinyl upholstery items, the outside metal surface of the car will get much colder than the interior. This causes moisture to form on the windows, especially on a cold or rainy day. Defrosters combat this phenomenon so that drivers can see out the windows and operate the vehicle safely.
The rear window on most automobiles has tiny lines going through it. These are actually electrical wires, which heat up when current flows through them. In this manner, the resulting heat is used to displace the condensation on the inside of the window, but can also work on the outside. The heating elements have very low heat so humans are in no danger of getting burnt if they are touched while powered on. They put out just enough heat to combat the moisture built up on the window. They are usually wired along the roofline of the car, underneath the headliner.
Some wew model automobiles are starting to come out with heating elements in the front windshield, as well, which will negate the need to let the vehicle warm up before turning on the defroster.
if need to say about alloy wheels refurbished, Most cars have alloy rims nowadays. And unlike steel rims, a fair number of these wheels leak air. It's not a bead-seat surface leak, where air can creep out between the rim and rubber, but a leak through porosities in the cast-aluminum alloy. Corrosion on the inside of the alloy wheel, causing air to leak. This is easily repaired with an inner refurbishment of the wheel.
