In this video I am demonstrating how to use a stud-nail gun to repair a small minor dent on a panel. Obviously there are more than one way to repair a minor dent. For example, you could use PDR (paintless dent removal), hammer and dolly, etc. However, this demonstrations is specifically for using a stud-nail gun to remove the dent.
This tool tack welds a small nail or rod to the panel. Once tacked you can use various tools or methods to pull it. Once you are done pulling the nail can be removed. This may require wiggling or cutting the nail with dyke pliers.
1. The first thing you want to do is to remove the paint coatings. The nail will need to tack to bare metal. (Note: this is for metal only. There is a similar tool use for aluminum. Also, in the video I am using a 3′ grinder, but care must be use not to over grind the metal. With newer metal that are very thin you may consider using a DA sander to remove that coating)
2. Attach the stud nail to the panel. Remember the first in last out rule. In other words, reverse the damage sequence.
3. Use multiple push and pulls. Always try to find the high area to push on while pulling the low out. Single pulls will cause stretched and undesired results. Roll the metal back to the original shape…not force. Therefore, I do not encourage using the slide hammer toll. Use this only as last resort.
4. Once the metal is straightened, cross grind or sand to clean the metal and provide proper adhesion for body filler. Be sure to grind or sand 4″ inches past the damaged area. This will eliminate applying filler on top of your painted surface.
Now you are ready to apply your body filler.
