    I have a dent on the quarter panel on a 67 camaro that you can easily reach from inside the trunk. The dent looks like a soccer ball whacked it. I opened the trunk and popped it back out and it looks fine but if you were to push a little on the out side it pops back in. My question is, do I have to heat it up and cool the metal to get it to shrink or should I use a dagger shrinking hammer or something like it to shrink the metal?

    Thanks.

    If you have a shrinking hammer and shrinking dolly you can try to cold shrink it without heat.

    I’ve had good success with both a shrinking disk and a small oxy torch that I’ve got. The disk is almost addictive it works so well.

    can you show me a shrinking disc? :whistle: I am still learning the ropes.

    Thanks

    Thanks Berry,

    I have seen them before. Do you work the disc from the outside to the center or the other way to shrink the metal?

    i dont think a shrinking disc or heat is nec. just hammer the steel around the dent

    Well what ya got for tools? It isnt necessary to spend $100 for a disk or a hammer and waffle dolly. I hear good things about the disks but the shrinking hammers and dollies [spiral or waffle type] simply dont work on heavy sheet steel like your working on a 67. If you have a unispotter type stud gun you can use it by simply holding the trigger extra long on the highest spots in your repair, you can use an oxy acetylene torch to heat and quench it or even a small hand held propane torch. In a pinch you can just weld a small bead on it with your mig to suck it up.

    Glad someone else does that on occasion to. :blush:

    I do have a mig. Just lay a bead across the middle and grind it off? That should make it where it wont pop in and out easily?

    That sounds easy enough.

    Thanks.

    You work from the highs to the lows. Keep a squirt bottle of water to chase the highs down. It’s pretty cool to work with the metal – not against it (it almost always wins). I’ve successfully shrunk 18ga with my disk without issue. It’s easier for someone starting out to use this technique than playing with a torch IMHO. I’ve always found a great deal of satisfaction in working out a high or removing oil can from a panel with just my disk, some water and time.

    If your new and just starting out an Oil can is a B to learn on by your self!
    You can do more damage than good very easy! Very FAST! Stay away from the welder!
    and the Torches! just speaking from experience :blush: :blink: :unsure: Bad memories! :cens

    Try a Disk first easier to learn shrinking with a disk.
    Plus its harder to damage the panel with a disk!
    Over at 101 some one sells them with a training video

    You guys mention that there is highs, in fact that it is almost perfect when I pop it out. The problem is if you push it with a little pressure it will pop back in.

    To me that means its stretched, right? Whats the best remedy for this a shrinking disc?

    Do what Bondo says he’s my Hero! :rofl

    Seriously Do post some pics!
    See what the guys say before doing any thing, youll be glad you did!
    I ended up getting so frustrated with an Oil canning roof I ended up destroying it :cens and had to patch the whole roof…. :blush: It wasn’t pretty. :blush:

    Hind sight is always 20/20 and now I wish I had listened more and worked it more before getting frustrated and doing what I had done. :blush:
