^That's an interesting tool, but I'd be worried about getting impatient and letting it heat up too much or wanting to spin it faster lol
I was surprised at how many warning stickers were on my bike when I picked it up. The dealer took off the nastiest offender--a large white and orange warning label that covered most of my rear fender. There is still one covering up any visible handle bar chrome that I'll have to work on another day. I took two large, ugly warning labels off the gas tank this past weekend at my parents' place since my mom has a professional hair dryer that gets to the perfect temperature for the job to avoid any issues with ruining paint. I used a debit card and a ton of patience to remove it and then Purell/ hand sanitizer to remove the residue left behind. The second decal was another story. It left behind half of its size in a much thicker residue. The hand sanitizer worked for most but then I stepped it up Goo Gone for whatever was left since I found a bottle in the garage. If that didn't work I would have moved up to WD-40.
Basically, you need a ton of patience for whatever way you choose to remove warning labels, logos, decals, etc. In my case, each label that I removed is printed in the first few pages of the owner's manual anyways.
