Thanks for that Matt, that's a great explanation. I had aluminium panels repaired (or should I say, tried to) years ago and the guy said no problems. When he tried to do them, it ended up worse than what it was. Obviously I was really pissed.
I have another car that needs a few dents pulled out, not aluminium thank god. can you pm me when you have time to come out? I'm in Hornsby area, or I can come to you.
thanks
Eugene
