I've always had a fear of catching stuff on fire with a blow dryer. lol I bet you could do that with a blow dryer, but I bet the heat gun is better to use, because it has an even temperature and pressure. Us artists have to go through a lot of trial and error to see if something works so we can get the artistic effect we want, so it won't hurt to try the blow dryer, I would just have a fire extinguisher close by just in case. lol
