I am at about 90% with the metal work on the drivers side 1/4. Wife was out, so I spent a good solid 4 hours tonight. I am really happy with the way the quarter panel turned out. I gapped the door at the 1/4, then decided to tackle the passenger side.
The panel to door fit on that side is better, but the door is sitting nearly 1/4" forward from where it should be. I decided "screw-it" I'll regret not fixing it, so I ground the lesser amount of bondo off of the 1/4 at the door gap and went to work. I used the shrinking disc to warm up the metal and move sections of the flange back.
Probably not the best way of doing it, but I'll go to work dollying and shrinking the panel back to fit the door, while removing any bondo.
I wish I simply would have done all this work myself to start with.
Oh well live and learn

If you are finding that disc is too big for that area take a small 3in rolec grinding disc and ground that disc smooth on some scrap metal. Then run that disc over the area to be shrunk. Works great on small areas, as ALL you are doing is heating the metal...Eric

A couple pics
I made a little more progress tonight.
One of the difficulties I was having, when shrinking inside the scallop, as it tightened the metal, it was changing the slope of the ramps going in and out of the scallop.
After less than stellare success, I tried heating the metal with the shrinking disc, then while it was warm/hot I used two dollys to persuade the metal to go where I wanted. It actually worked fairly well.
I think I have about another 4-5 nights work to get everything exact, where I can use an absolute minimum amout of filler.
Thanks for the tips

How much of a dent are we talking? If it's very shallow, there could be a low spot because the metal is over-shrunk, or because it's stretched. Can you push it from behind and have it pop out into a bump, then go back like an "oil can"?
If so, i'd guess it probably needs more shrinking. If you can't push it back out, it may be overshrunk and need to be worked on dolly to stretch it a bit. But don't do that until you're sure that that is what it needs.
A little light sanding with some sandpaper on a flat block can show what's going on, by highlighting high areas. A stretched dent will look different, it will have a high ring around it. A shrinking disk would fix that right up.
Photos might help.

|baddbob||quench on the same side, if you shrink it too far and take to much of the crown out of the panel you'll need to hammer some crown back in. Sometimes you can use a rubber mallet or plastic mallet or a wooden mallet so you don't get any hammer marks.|

Can I reverse shrink, by doing this?
I have been working with the shrinking disc.
Things are going okay, and I am learning.
What I was wondering; If I quench the metal on the reverse side, will it shrink out? or do I need to stretch the metal with a hammer and dolly?
Normally I have been quenching the metal on the same side as I heat on to shrink down.
anyway, any tips appreaciated... I just don't want to beat on this panel if I don't have to
