Ugly paint

This picture really doesn't show it, but the paint is in bad shape. It has been repainted sometime in the past. From years of exposure to the sun, crap sitting on it and the improper storage, it is dull and very scratched. Color sanding and buffing might bring this paint back.

 

Honey, you REALLY killed the paint!

Here is how the color sanding process works. Take 1000 grit wet and dry paper, wet sand the entire car. Feather the scratches out. Be careful and ensure you have a lot of paint on the car because it is easy to sand through the clear coat, or even the paint to the primer. Clear coat paints are better to color sand than others. If the car had a quickie cheap paint job, this process might not be possible.

 

Scratch

Here is an example of a deep scratch. Color sand the entire car and work the scratches out if possible. Take your time.

 

Fender sanded

Here is the fender with the scratch sanded out. This car was painted at a quality shop because they put a lot of clear coat on. There were some deep scratches that some aggressive sanding took out without breaking through the clear coat. Again, this is not possible with a low buck quickie paint job.

 

Scrape

Here is an example of scrapes that are all over the car. You also might see the paint as being dull and contaminated.

 

Door sanded

Here is the door sanded out. It looks dull, but the scrape is gone. There are so many boo boos in this car that is taking a few days of after work time to get them all. Chips on the front of the car will be touched up with touch up paint.

 

A flat black BMW

Here is the car after sanding with the 1000 grit paper. The 1000 grit is aggressive enough to sand the scratches out but is not so much that you can sand through the clear coat quickly. Take your time and do it right now.

 

Scratch ID

After wet sanding for a few days, most of the scratches are gone. When the car is dry, look over the paint carefully. Visible scratches are marked with a sharpie. Be careful that a scratch is identified, not towel lint. (it looks the same.) After all the scratches are gone, the car is sanded with 1500 grit paper to further smooth it out.

 

Sanding scratches and imperfections

The marked areas are sanded until all is gone, including the marker.

 

Boo boo gone

Here is the fender with the scratch sanded out. It looks like this paint might be saved after all.

 

Enough!

The color sanding process is complete. I could go over it again with 2000 grit, but this is really not needed. The buffing process will bring the shine in and remove the sanding marks. Besides, I still have clear coat left. I did not break through it anywhere.

 

Buffing

The buffing begins with rubbing compound and a wool bonnet on the machine. It looks better already. After this is complete, the car is washed.

 

Polishing

Next, polishing compound is used with a foam pad to remove the fine scratches and swirl marks from the buffing.

 

Wax on, wax off

After another wash, a good quality wax is applied with the orbital polisher. 3 coats were done.

 

Done

After hours of work, the paint looks a lot better. Now those damn hail dings show up (about 8-10 between the hood and trunklid). These will be fixed whenever I get to it. I might keep them to add charater.

 

Outside

Wow. A different car than what was dragged home last year. For an investment of less than $100 (including the cost of the buffer) it was spared from a $3,000 paint job. Too bad though because black paint is hard to keep up, and an excuse to paint it another color would have been nice.
