RE: Ivan's coupe <blast off>
Dave, the no big holes bit can be explained by the preceding pages of this age old thread.. Not much luck, but lots of square ft. of fresh sheet metal.
I'm still searching around for the best method of getting the roof back in shape. Have seen an approach where a dent is raised back into position and then lightly hammering the circumference of the dent.. that's more or less stretching the metal. And then there are approaches like raising the dent back, heating it and rapidly cooling it (found some variations on this theme).. that's shrinking I would say.. So question nr 1 should be did the blasting cause shrinking or stretching? Dont want to get it wrong because the chance I would make things worse is very large. May even consider adding additional roof support beneath the affected areas if all else fails.. Informed suggestions on the matter are most welcome. [edit] Some more google-fu suggests blasting causes stretching of metal, shrinking is highly unlikely given that the media is blasted on with pressurized air that is typically quite cold. That little nugget suggests that shrinking strategies are probably the way to go. FABRICA MI DIEM, PVNC! |
