My 71 has a bathroom counter which I believe is ABS. I know it is not fiberglass. It has cracks which so far I have not been able to fix. I fiberglassed and screwed the counter to a plywood base to stabilize it and have tried to fix the cracks with polyester resin, bondo, 2 part epoxy paint, other paint, and superglue and the cracks magically reappear. My hypothesis is the ABS plastic has a high coefficient of thermal expansion. In other words, the stuff expands and contracts with the temperature but the cracks don't.

I could cut out a formica insert and attach it to the top serface.

I also am considering covering the whole counter surface with wood veneer. That would require bending the veneer around the curved edges where the top transitions to the side. I have never worked with veneer. Do you think this will work?

Also I need to replace the plastic trim on the counter. The "edge nosing" is available from Inland but I don't know if the inserts that snap into the extruded aluminum frame is available. Any alternative suggestions? Formica?
