[Healeys] Bodywork Advise on "Oil Canning"

[Patrick and Caroline Quinn]

G'day Mark

Rich is 100% correct. In my dim dark past over a period of 9 years I
attended a motorbody hand forming course at a technical college in Sydney.
It was an interesting collection of classic car enthusiasts including a
judge, stockbroker, opal dealer, teacher and company directors. We
repeatedly failed year after year so we could keep going back. We had a ball
and repaired lots of things and one bloke managed to restore his Aston
Martin DB4 during the time.

You cannot repair a 'tin can' effect with filler as it will eventually pop
out. Even using lead filler won't last either. 

You need to remove the paint, heat the metal and beat the judicious crap out
of it until the metal has shrunk sufficiently. You may have to do it in
multiple places until the metal has shrunk enough.

Mark,

 Do NOT try building it up with filler. The proper way to repair would be to

have it stripped bare and have a skilled panel beater heat it correctly and 
hammer the welded area to shrink it back. Amazingly the skilled man can 
bring it back to the original flatness it was.
