Fading paint...

Of some strange reason, the paint on my left side panel is fading -- it looks like sun damage or some kind of oxidation going on. Anyone knows how to treat this, perhaps there are some products that can be used to buff it out? My Box is a black '98.

Any help appreciated,

Has the car ever been in an accident? Is this the result of some body work perhaps?

A good paint polish will help restore the luster -- especially if you apply it with a random orbit buffer, and follow with a sealant (or wax).

Here is what I did to get my '02 Basalt Black Boxster looking good:

Hi, Hope this hepls

Bringing back the shine to dull paint involves two crucial tasks. The first is to remove every bit of old crud and oxidation now smothering the paint's shine as these are signs that destructive layers have actually depleted the paint of its protective oils. The second task is to reintroduce these protective oils back to the paint. There are many products out there to achieve these two tasks. Rubbing compounds containing a slightly abrasive material, or cut, to remove oxidation will achieve the first task. The second task will be achieved by applying polishing compounds containing a milder cut and the oils required to bring back the shine. These products will achieve the second task. Some products bridge the gap between the two. Which product to use is determined by how depleted the painted finish has become.

For some swirl marks along with a water spot or two, a mild polishing compound will usually do the trick. For chalky, dull, heavily oxidized paint, a more aggressive rubbing compound is first required to get the paint ready to accept the polishing compound. A third and equally important task after either a rubbing or polishing compound has been used is a good waxing. The wax keeps bugs and other bad stuff out of the paint, and all of your rubbing and polishing work sealed in and protected against the baking sun, soda-hurling kids, and other harmful elements.

Paint Types
The first and most important thing to determine before starting is the type of paint your vehicle has layered on its body panels. Most automobile paint falls into two categories. The first type is called single stage. This paint is applied in one shot, and is uniform in its thickness. The second type is known as basecoat-clearcoat. Basecoat-clearcoat is applied in a two stages. The dull basecoat contains the color, and goes on first. The clearcoat is applied second, and gives the basecoat-clearcoat paint job its real shine. Since the clearcoat lies on top of the basecoat, it takes a beating from the elements. Extreme care must be taken when using rubbing compounds, polishes or other products that contain any type of abrasive cut in them on basecoat-clearcoat finishes. This is especially true if using power tools such as a high-speed rotary polisher. If the clearcoat is compromised, the only way to bring back the shine is to apply new clearcoat—an expensive proposition at best.

Before using any rubbing or polishing compound, remove all old wax, dirt, and grime by washing the vehicle in a shaded area if possible. If not, be sure to at least park the vehicle in a shaded area before drying it and applying any rubbing or polishing compound. It's crucial that you never use rubbing or polishing compounds in direct sunlight the product can quickly bake itself into hot painted surfaces. Work in small overlapping areas so you can stay ahead of the product, and the process. You'll soon be seeing your smiling reflection looking back at you from your shiny, preserved paint.

Step 1 - Clean and dry the vehicle, preferably in the shade. Test all products on an inconspicuous part of the vehicle to get a feel for how they work.

Step 2 - Apply compound by hand, or with a buffer turned OFF, to work material evenly into the buffing pad and the work area. Buff in lengthwise strokes with the bodylines of the vehicle. Do not work in circles as this can show up as "swirls."

Step 3 - If available, use a random-orbital buffer. If using a circular buffer, be extremely careful not to burn through the paint or clearcoat. Let the product do the work. Lengthwise even strokes with light pressure are key.

Step 4 - Make sure to remove all of the rubbing compound before moving on to polishing. Polishing compound is applied in the same way as rubbing compound. In general, use the most aggressive product first, followed in sequence by less aggressive product or products.

Step 5 - The results speak for themselves. Regardless of which type of product you use, always apply a good coat of wax as a final step and on a regular basis thereafter to protect the paint, and prevent oxidation from starting up again.
