I am a welder and yes i know about metals but it seems fishy to me how airduster and a heatgun can pop a dent well i just got a hatch well worth the trade the bondo jobs bad but im cutting it out and replacing it with a new QP up above the passenger quarter window is a crease dent not bad enough to put wrinkles but I cant push it out with my hand and near the duck bill the is one too its sorda shallow but still no wrinkles could this air duster thin possible work i can not post pictures at this time bc im on my friends pc and my car is at home

 

No it doesn't work.

 

It can work, but isnt the correct way to do it. All you are doing is shrinking the metal via heat so it can weaken the metal. I use a small torch and air to remove hail damage..

 

Well i decided just to have them pulled and worked with fiber and bondo i got a real good price off my dads friend who owed dad tons of money so im paying like 100 bucks for tons of work even reprimering and gettin paint once i get 400 bucks so he and dad can be even hellz yeahh :p
