the way i would go if you want a dent out without having to put a hole in it an pull then use body fill or just use body filler without pulling first.... is there is a company called Dent Wizards they use a high power suction that will even pull out a pin head sized dent - i called them up an they acually will come to your house but i went to them because i didnt see in any point in paying for them to drive an charge me w/e the crazy price would be... but i had 3 dings on my driver side door an crease on the back lower left quarter - so i took it to them an they made the car look as if there was never a dent there in the first place with out even fuckin up the pait - that is the best way to go if you want a real nice job done with out canabalizing your cars body an adding un-necessary wieght to it.... this is the site for them ...
