Careful with the heat gun, loosen the paint and you'll be bummed. I seriously doubt you'll get that with hot n cold but... least agressive method first works for me. That sounds good on the match then, chicks can SPOT that stuff right away. The hot glue deal involves plastic studs and puller, not something easily duplicated at home but a no-sweat try-and-see at a PDR place. That is, unless they look at it and go "nope.". I'll take a stab at body shop price for that... seems like an hour or half hour for the dent, 2 or 3 for paint n rub... I bet somebody might professionally hook it up for a couple hun. Weight that against failed tries plus then having to bodyshop it anyway. Just sayin. I may be just throwing too much kindling on the fire here, you think on it bud.
