At some point in the past, I remember a TOH episode where Tom Silva was repairing exterior molding with some sort of spray foam. He created a template of the existing molding, sprayed on the foam, and then ran the template over the foam so that it matched the profile of the existing molding.
Does anyone else remember this or know anything about this type of product? I have a small piece of molding that I need to repair, and this would be a great way to do it.
Thanks in advance for your help with this.
