If you get a good company then yes they will get the dent out without any paint ! How bad is the damage ?
It's too difficult to photograph ......it's basically an L shaped dent in the door panel near the front . I've shown it a fix a sent guy now and he's not certain he can do it. He's going to come and have a better look when I'm back off holidays . He seems like he wants to have a ho at it. But not guaranteeing he can fix it? Seems like a strange basis to engage him to me
I am PDR trained so know about the process, in a door there is about 15-20% you won't be able to get to. So if i was you just explain to him if he has a go and can't get it all out you won't be paying him in full or not at all. Also make sure he doesn't drill any holes for access into the door !
In them cases though they use glue and tabs and a puller hammer.... Had that done on mine when its doubled skin
The way it would go about it is (don't PANIC it's only 5 bolts and a wiring clip) remove the door and use the access hole for the wiring loom to get to it. I would say it will come out ok.
