I just found 2-gal of DuPont URO 1140 Primer Filler in a box on the shelf from a project we started 20 years ago. There is a gallon of Convertor and a quart of Activator also in the box. Is this stuff still any good? The paint still shakes/moves in the un-opened cans...
If it's OK to use, is it compattable with new top coat paints?
Thanks,
Mike B
