Use it on interiors and exteriors. More than just arched, ellipse and half round windows. Have opened molds for all the LP SmartTrim sizes in both cedar grain and their new smooth for use on the exterior of homes. Great product and it will far outlast anything else on an exterior.
Have you looked at the posts you are responding to. 10 or more years old. Do you sell flex trim? If not, why would you search for such a random thing?
