Chip Repair and Airbrush

Well, I am 24 hours into my repair. I have been documenting with a disposable camera that had a few pictures left. This weekend I should have pictures posted of the entire project from start to finish.



First I washed the area with dawn and cleaned again with denatured alcohol. Next, I sanded the interior of the chip (size of a nickle) which was down to the plastic on the bumper with 320 grit sand paper. I removed one island of loose paint in the center. I then feathered the edges with 800 grit sand paper. This was done using sand paper cut out with a hole puncher and glued to several pencils. After the sanding I washed the area again with dawn and used an alcohol swab.



I taped off the area around the nick then overlayed that with newspaper with a hole cut in it. I taped the newspaper back and now I have my canvas, the only exposed area is the nickle size chip. I took two passes with automotive primer at about 10inches, set up my portable heater and allowed it to dry for 45 minutes. I then returned and made two more passes and allowed it to dry overnight.



This morning, I am going to sand the primer down to just inside the chip with 800 to 1000 grit sand paper then use the airbrush to lay a few layers of paint. Afterwards, more sanding with 1000 to 1500 and wet sanding with 1500 followed by polishing with 3M Swirl Remover for Dark Cars. Lastly, a wash and then coat the car in PUPP.
 
As promised, here are the pics. Unfortunately they did not turn out well but you can get the idea.

6)Another angle showing the chip above the paint. It looks darker in this picture but the paint was only slightly darker than my paint plus the surrounding paint has been cleaned with dawn so alot of scratches were showing.

7)And the final sanding...I wish. Unfortunately there were a few edges that I continued to wet sand and the primer started to show through on the chip. I tried to touch it up but another chip broke off of the primer...thusly my attempt failed. If I had stopped at this last picture you could not tell until you got about 5 inches away. Since it was on a corner, it reflected a little different than the surrounding paint.
