Hi,
Yes, the dent repair folks do this sort of thing all the time.
The one problem that can be encountered, is whether the backside of a panel can be accessed?
Sometimes, at the very edge of a panel, where two pieces of sheet metal come together, it will almost be impossible in those areas.
Others, where there's bracing on the inside of the panel, they have to drill-make a hole so they can get a tool through to the dent.
Then they usually plug the hole with a plastic plug of whatever size needed.
Not much choice in those instances, and I reckon it is the better of the two evils.
Downside with this sort of repair, it can be costly. I've had this happen two times on my Tahoe, small little dents that I put in the door. Each instance, the one dent was $50. But, when the little dent is totally gone, you sure do feel a whole lot happier.
Usually with a good number of dents, the price becomes less per dent. They should be able to give you an estimate up front, and there's the possibility of insurance covering such?
The first time I had this done, there was a black BMW being done before me that had hail damage, and a boat load of other small dents, that the vehicle looked like somebody took a ball pein hammer all over the car.
When he was done, there was not one dent anywhere. I was amazed.
