Well after starting two weeks holiday I decided to have another go at the back panel,
so I started on the LH side and managed to stiffen that area that now has bondo on it,
this gave me confidence to try to fix the rest of the panel and after two days on the shrinking disc,
I felt I had beaten the oil canning problem, so I was very happy about that and
saved myself the cost of a proffesional bodyman to fix it.
A smear of bondo was applied, sanded and more applied till the panel was smooth
So a light coat of etch primer was applied, I will now finish the lower body swage
and then the sides will be massaged and finished.
