I realize that they are basically going to 'tap out the dent' and I'm sure I could try it on my own, but I'd rather have professionals do it as they have the right tools and know-how. If I did it and messed up, it would only irritate me more.
I don't expect it to be perfect, just better than it is now. They will seal it and touch it up to look good again. So long as it does not look worse, them doing it is probably my best bet.
Of course I would rather have it done perfectly, but if I did that with all ding/dents my truck will get over the many years, I'd spend a fortune!
