Things that affect your car paint

A better looking car means a higher re-sale price. The first thing you will notice is how easier your car is to clean – water just runs off it and a quick wipe with a microfiber leaves a brilliant shine. Any blemishes should be removed as soon as you spot them using the appropriate product. That product should be a wax less based product as to not neutralise the bonding formula of the paint protection product.

In most cases a wipe over with Car Cares Waterless Wash and using the appropriate microfibre cloth is all that is needed. Using other cloths, such as cotton etc can cause scuffs and scratches.
What that extra layer has given you other than making you car look good – is a little longer time to deal with any problems.

Thing that affect the paint are:

Road Contaminate: If over a long period of time oils, dirt, tar, exhaust and other pollutants build up they combine to affect the paint finish

Nature: Tree sap, bird droppings, insects, salt water and other natural deposits can, if allowed to stay on the paint work, leave an etching or scarring. All of the above should be washed off as soon as possible.

Environment: Industrial fallout and other man made products may react chemically, damaging paint work. The easiest way to keep the paint work looking great is to keep it clean. However many of the worst problems can be caused by poor cleaning practices and the use of wrong products.
