If you're working with resin, you might be wondering if you can use a hair dryer instead of a heat gun. The answer is yes, you can use a hair dryer to heat up resin. However, there are some things to keep in mind when using a hair dryer. First, make sure that the hair dryer is on the lowest setting. You don't want to overheat the resin or it will become brittle and break. Second, hold the hair dryer about 6 inches away from the resin so that it doesn't get too hot. Finally, move the hair dryer around so that all areas of the resin are evenly heated.
