Cars with a vinyl top. It can't get much more classic. On the negative side: The vinyl jacket - provided with fresh showroom shine if necessary - can hide a lot of miseryn.
First of all, check whether the vinyl is simply glued all the way around and check it for damage.
Then look over the surface with eyes and fingertips. The vinyl was once pasted over the painted plate. And between 'ever' and 'now' water may have come between the steel and the vinyl. In this case, drainage points are usually the 'holes' in the vinyl, the recesses for side windows in Landau models, possibly decorative piece on screwed-on parts.
What a little moisture can do if it is simmering for years under a plastic cover is incredible.
Replacing a vinyl top is not even the biggest job.
But if so much brittleness and holes are released after peeling the old vinyl that a civilian capital is being added to welding work?
You don't want that!
