DA sanders are basically dual action sanders. There is a huge variety of models available and the really important thing is to find one that has really high quality. You want the sander to cut right through the surface of the paint in a manner that is completely controlled. These devices are named this way because the head will move in 2 different directions which is more effective and faster.

Most people are going to use the old paint as filler so that they can apply a secondary primer coating. A DA sander will help out in doing this but it will also reveal the vehicle’s history as it exposes previous primer and bodywork.
- DA Sander Safety Facts
A DA sander is really easy to use but it is still recommended that you pay close attention for your own safety to the entire process and that you are not going to be distracted. You should wear a high quality respirator or a mask so that you can protect your body from primer debris, dust and paint. Also, the area where you are going to sand should be properly ventilated at all times.
- DA Sander Discs
When you go to a specialized store you will quickly notice that there are many discs that you can buy. You will need to always make sure that proper grit is utilized in order to cut paint surface. If you choose the correct disc you will notice that you will not leave any scratch marks while sanding. Make sure you look closely at these sanding discs. A number is noted on its back and the manufacturer can offer an indication as to what the number means.
A sanding disc is really easy to both fit and remove because of an adhesive that is placed on the back of the disc. You should never use a disk on top of another and the DA Sander’s head needs to always be in a proper working condition. If this is not the case you will find that the sandpaper wears unevenly and even scratches the very surface you are trying to smooth. In addition, when you are sanding the sander has to stay flat on the metal surface where you use it. You do this so that you can avoid surface gouging.
Specialists recommend that you constantly change the sanding discs. As soon as it becomes clogged with debris you will have to use another one because you will end up with scratches in the event that you keep going. In most cases you can just use a disc for a few minutes at a time.
DA Sander Speed
Most DA sanders will have special adjustments so that you can control the head’s speed. You need to make sure that the speed is fast enough and not too slow as this would cut poorly. If the speed is too high you will end up burning right through the metal. Keep in mind that there is no way to know if you are sanding correctly. The only real indicator is your own personal experience and in the end you want the entire surface to be smooth. You should also keep in mind that the area you work on needs to be wiped down every now and then so you do not end up with rough edges or raised areas.
