I used a heat gun for about 20 minutes. It still wasn't good enough to loosen the seal. It is a diffcult project. The chance you will ruin a tailight is very likely. Also, be careful where you pry from, you can scratch the black on the inside of the lense or crack it like I did! I think it's much easier just to save that money and put it towards the real deal. But if you can't afford it is a crap shot. Best a luck!
