Snowboard rub on wax?

I am currently looking for ways to wax my snowboard without using an iron because sadly we only have 1 and my parents wont let me use it. So I did a little searching on amazon and found this "rub on wax". Its called "Whacks Wax Rub-on Ski & Snowboard Wax ". "It says Whacks Wax speed in a rub-on form! Take it with you to the mountain, use it at home" The product description says "We went back to the laboratory to cook up a rub-on wax for our customers, and we succeeded. Our rub-on ski wax combines the Whacks Wax speed known and loved by skiers and snowboarders across the world with the convenience of a rub-on product that can be used anywhere, anytime. Each purchase includes two 2+ ounce pieces of wax (or one 4-5 ounce piece), which will last many, many applications. " What I want to know is if I need an iron for this. Thank you
