not at all man,......goto auto zone or w/e and get some "Sticker Be Gone" or Goo Gone, drench the H symbol with it, let it sit for a min or two and use a plastic puddy knife or even a credit card. Go slow and dont force it, then as your doin that spray more of the stuff onto the emblem, take your time they come right off......then I washed the spot down and made sure all the sticky stuff was gone. Dry the area, and peel and stick the new one on!
In my own opinion I would say use SFR just because everything I have gotten from KDMguy has been amazing quality, and fast shipping. I have heard some bad stuff about other badges breaking off, but never about his.
Get yourself some fishing line and some 3m adhesive remover. Heat the badge up with a heat gun, then take the fishing line, and saw it back and forth behind each item. Then use the 3m stuff to get the goo off.
