I own a heat gun but the day I decided to remove my vinyl lettering the heat gun was at home and the hair dryer was on the boat. Why I have no idea as I never blow dry my hair but ANYWAY it worked just fine and I had the old name and hailing port removed easily and in short order. Maybe if you are dealing with stubborn stuck on vinyl the heat gun would work better / faster but the hair dryer worked out just peachy for me. And I did not need to use any chemicals. Really it was ridiculously easy to get off. I guess I got lucky.
