INFERNO
I always wanted to be a firefighter when I was a kid... hence my great love of Inferno. I've probably played with him more than any other Transformer I have. Because of this, he brings new meaning to the phrase "chrome wear". It's blackened just about everywhere. His stickers were also worse for wear.
Delta Star's stickers have made a great difference, as you can see! He gives extra stickers for the circular stickers, which is great if you make a mistake!
The only slight problem is with the stickers that go on the front of Inferno's shins. I have found that because the stickers have to bend so much, they tend to come unstuck. I've solved this by scoring the sticker using the back of a scalpel. This helps them stay bent, and they haven't come unstuck for a while.
I believe that Delta Star has now got a far bendier substrate for his stickers which should alleviate this problem. We'll see when he does a set for Grapple!
