I found a product called Flextrim that makes a variety of trim types. It is advertised to have properties just like wood, it can be painted or stained, screwed, nailed, cut cleanly, etc.
The website is: Flexible Trim by Flex Trim
There are several online vendors which carry it.

It came up with several in my area. Just enter your zip, search radius(miles), and # of returns to display.
This sounds just what I need for the bathtub molding, for where the floor meets the vertical panel. As my tub has a rounded end to deal with. I would imagine it would be great for any application in the AS, because of it's ability to flex/bend to contour any angle.
In my opinion this is a priceless find, as the AS have many obscure angles/bends to navigate while restoring/remodeling. I hope others find this helpful.
