tips for repairing dent in door

Like said above when it oil cans in there will be a high spot around it. Find that high spot/crown, eyebrow as it was called, I usually mark with a sharpie so I don't lose it. Hold the panel out and tap the high spot around the low spot. It usually doesn't take much to put tension back in the panel. I use a pick hammer with a sharpened point and I strike towards the oil can to move metal that way. Just taps, no need to frail it. Hard for me to say without looking at it but heat shrinking with a torch can really move some metal and I wouldn't approach an oil can that wants to stay low with it. If i shrink it's usually with a stud gun and shrinking tip. A lot more controlled. The effects of shrinking can be hard to undo if things don't move as anticipated.
