Anyone have any problem with this? I've always put Marglass or Duraglass over epoxy primer when doing restorations and I have a factory seam where the body panels are overlapped then spotwelded together; this in lieu of using lead and in lieu of putting the Marglass right over coarsely sanded bare metal like the directions on the can say to do. I've never had a problem with doing this, at least that I know of, except for bubbling under the paint once. I read the bubbling can be caused by the heat of buffing over the fiberglass filler: I don't know if this is true or not but it sure ruined the paint job.
I avoid spreadable body filler like the plague, but sometimes using it can't be avoided. The alternative is using lead which has its own issues, but maybe they are less in the long run. The majority of failures I have had in my own work and seen in other's work has been in spreadable body fillers wreaking havoc down the road. With others' work I've had to redo in my shop it has been with people who have either used way too much Bondo (or something similar) in one place and/or putting it on over bare metal then the metal rusting underneath the filler. I don't do this so I've never had this happen, but I've had other problems with it (such as it shrinking over time) depite my best efforts to do everything I can to make it turn out successfully.
But I digress...
