Just got my badges through - thanks pasty. I had the idea of putting them over the old badge to give that concaved look that i prefer as opposed to flat, but what is the best way to do it without getting any creases, or are they so stiff that if i try to bend then round they wont stick down properly.

They're quite stiff, so can be applied over the original badge without an issue

Make sure you fully degrease before applying...IPA is ideal or meths
