A recent project I have been working on involves some flexible molding. I thought I would post some of the sources here:
It should also be noted that Outwater Plastics carries flexible moldings as well.
I have used them a couple times previously and they are pretty nifty.
A couple of things to keep in mind:
-you can order off the shelf profiles, or match existing molding
-the size can be slightly different than off the shelf profiles, and may vary slightly in the curve.
-some curves can be produced off the shelf, others have to be ordered - so leave time in your timeline to accommodate
The moldings do create some nice results!
