Things You'll Need
- Electrical outlet
- Hair dryer
- Air duster
- Damp cloth
Instructions
Plug the hair dryer into an electrical outlet so that it is within easy reach of the dent. Make sure that the air duster, like one used to clean computers, is close at hand.
Switch the hair dryer on to the highest heat setting, and position it so that it is almost touching the dent. Slowly move the hair dryer back and forth around the entire dent for one minute, heating the surface. Turn off the hair dryer.
Quickly turn the air duster upside down, which will make it release liquid carbon dioxide. Spray the dent on the horse trailer with liquid carbon dioxide for 30 seconds.
Watch as the difference in the temperature between the heated metal of the horse trailer and the liquid carbon dioxide causes the dent to pop out.
Wipe off any remaining liquid carbon dioxide from the horse trailer with a clean, damp cloth.
