Re: Fixing roof dent?

Johnny K opined in news:    You dont have the skills to do it, you're not going to acquire them soon... and no one can "tell you how" It's called "oil-canned", and fixing it is an art.A >>>>GOOD

Stephan Rose · Accepted Answer

Heating the metal then cooling very fast (using a wet rag for instance) it will cause the metal to shrink, hence removing the dent. However....as backyard mechanic said. Unless you know exactly what you're doing, how you're doing it, and why you're doing it.....don't reccomend it to try it yourself.

Bah.. I Pick up quickly.. and having someone come over and fix it isn't an option.. :) But what I've been debating is, heat around the crease, (hardly any at all), or heat the thing.. so you think dousing with dry ice is overkill?Backyard Mechanic wrote:

Heat around the perimeter to shrink the metal...Quench with cool water every few inches..Beware that this take a truly delicate touch, and you screw things up badly if your not careful, forcing you to replace the roof panel.......Once again, not for the amateur.....................

Aight.. But I was under the impression that heating the perimeter with a   torch would warp the whole roof?Bill S. wrote:

I also assume you mean heat with oxy-acetelyne.. not propane or something of a lesser heat?Bill S. wrote:

Not if you quench it every two inches...............If you have to ask for clarification, don't you think your in over your head (no pun intended)................Bill S.Johnny K wrote:

Nope.. never in over my head.. Go big or go home, is my motto.. And I'm not dead yet.. :) But i just like to get everyones opinions before I try something new. Someone told me that if I heat it, it will warp anyways, no matter how much you heat. Another version i heard of, is just pouring boiling water on it, then dousing with dry ice? Ever tried/heard of that one?Bill S. wrote:

Nope, don't know much about mustangs.. Or body work.. Thats why I can't wait to get to the mechanicals.. BUT, it's just not really plausible to have someone professionally do it, as it's just a shell, on a rotisserie, in my garage.. Unless I knew someone around me in the field, but I don't... what I had PLANNED on doing, was fix the rockers (doing that right now, ran into some other unforseen problems), replace the quarters, replace the frame sections, and floors (already done), fix the dent in the roof, then spray all that with whats left of my dp50.. I mean, i suppose i could do it all BUT fix the roof, and leave that till later, but that doesn't make much sense either (you wouldn't believe how much things like this keep me awake at night)..Scott Stevens

Johnny I'd tend to side with the others here. Moreover, I think your lettingthat roofdent distract you from more pressing issues. I'd get the car in a rolling formand thenget it to a pro that can massage it out when the final body work is read to go.You stillhave a lot of welding and bolting to do before  you reach the roof.BTW I'm calling a friend who has a local contact for vintage parts. I know for afact hejust scrapped a California bodied car that had been wrapped around a  pole inToronto, sohopefully he may have some good solid frame and strut rod pieces that can besalvaged. Thecar was hit hard in the cowl so it was pretty bent! It was a 'vert ( sorryBill!) StuK

Johnny K opined in news:    Well, like the guy said - It's your car.How'd that "measure once, cut twice" floor pan come out?

Johnny K · Answer

Great.. Well, I still have big blobs of weld to take off, but I mean, the pan is butt welded in there..Backyard Mechanic wrote:
