I purchased two different types of dent removers, the suction cup one and the one requiring drilling a small hole. The suction cup one did absolutely nothing. The other was able to sort of take out some of the dent, but its still not near perfect and I have 3 holes in my panel now. I think I'm going to just try and do the best I can by applying some Bondo. I've started to sand down the panel down to the metal. Anyone have experience using Bondo and have any suggestions?
