"outy dent" in the hood
« on: November 04, 2008, 02:12:18 PM »

I am preparing to paint the 300 with a black/gold color scheme (sticherbob's suggestion to a post I had on DryDock a while back). There has been a small outward dent right in the middle of the hood since I got this car, like someone closed the hood without enough clearence one time, it's not too noticeable, but I know it's there and would want to staighten/flatten before any paint goes on.
I'm thinking on taking it to a dent removal specialist, but without ever having this kind of work done on any car I have ever owned, I am a little skepticle.
What are the do's and don'ts of this kind of body work?

Don't knows how to remove the dent, on mine I replaced the hood because of rust issues, but I do have a good idea how you got it.  Mine appeared when the left motor mount broke and every time I stepped on the gas, the engine rose and the air cleaner mounting stud would hit the hood. Stupid as itr sounds, I drove around for a couple of weeks before I figured out why the hood was rising!

Fury440,
The engine mounts are in tact, but that doesn't mean the left one wasn't broken at one time. I kind of thought it was caused by the Moroso aftermarket air cleaner kit that was on it when I got the car. I have since replaced the air cleaner with a refinshed stock one.

A dent stretches the metal,so in theory you will need to shrink it back in.
From the under side,with a torch,heat it up,and then quench it with a cold wet rag.It should pop back down.
Hammer and dolly works,too but again the metal has been stretched so finnesse is needed to smooth it down. Tricky with a large panel.

CBarge,
 
If I were to use dry ice after it was heated, would that shrink it just the same?

Ah, put a six-pac hood scoop on it - forget the dent.
 
Besides, that way I can see how such a hood would look on a C without wrecking my own hood.

CBarge,
 
I never seen dry ice being used before.I saw a cold wet rag used by my body man guy who learned it from the old school.
 
The quicker you get it hot,the quicker you put the wet rag on it.
POP! and it is done.Careful not get it too hot or the hood will warp.
Keep the heat on the dent and not the surrounding metal.

You need a helper to heat the area a dull cherry - red, then you can hammer it down against a flat dolly, and then quench it with a cold water soaked rag. That is the way we shrink all sheetmetal...the heat excites the molecules in the metal, the hammering shrinks them back to the way they were, and the cold water sets the metal so it regains it's temper. This is the way we remove oil-canning of sheetmetal too. Larger dents need to be removed from the deepest part first and worked back out to the edges.
