It's probably more complicated than a simple glue and pull but that's the idea. My buddy just started doing paintless dents. He's been a body man all his life and he said it's a little bit trickier and takes awhile to get used to. You will still need some special tools(suction leveler with screw puller).

As for the chemical, I am not sure but I think it was alcohol. Make sure to put polish and wax after bc it will probably dry out the coat.

I have used this technique several times. but it is always different from time to time and where the dent are. but here is what I did.

clean the dent area, with alcohol, white sprite etc..

have the glue gun hot and ready.

take a new glue stick and place a lot of hot glue in the middle of the dent and attach the unused stick and let it sit for at least 15 min...

try then to pull the dent out with the glue stick.

remove the glue and stick with a hair dryer

you may have to do this several times if the dent is big or you did not pulled it correctly.

as stated you should always wash and polish the dent area after.

Hope this was any help:)

My wife got caught in a hail storm last year with softball sized hail (yes softball, size hail) and my X5 had hundreds of small dings on the hood, roof and tops of the door panels. I went to the local Cars Collision Center here in NWI to attempt the paintless dent removal, rather than replace the panels.

Checking the suface under black light before and after it was amazing. Not a single dent was left.

I say let a professional do the work, unless you really know what you are doing...

thank you all!
