Well, if you don't want to pay $85 per ding to get pulled, give the Ding King a shot. What's the worst case, you lose $20 or so?
Just make sure you clean the surfaces really well before you glue them, and be sure to get the glue as hot as you can, and let it set for a long time so that it dries properly.
Like I said, it probably won't be perfect, but it should be a big improvement if you did a decent job.
