I've got a lot of dings and scratches in my bath tub. How do I know what kind of tub it is to repair it?
There's also rust forming around the drain.
If there is rust it is not fiberglass. So it is porcelain over iron. Both kinds are reglazed the same way with a epoxy blend.
Just get a new bathtub because in this day and age people don't even use those tin tubs anymore.
Look online for bath tub repair kits and there are companies that will come to your home to do the repairs fairly cheap.
