The Pro-Trim Painted product is the perfect complement to all vinyl exterior products. It is highly impact resistant, substantially UV stabilized, lab and field tested. Pro-Trim is easy to clean and work with. Unlike aluminum it is virtually scratch resistant. It is bendable and cuttable on any brake. Many shapes can now be bent that would be impossible using aluminum. For example, porch columns can be bent in one piece and then snapped around that column without creases. Our patented WD3848 compound expands less than typical vinyl siding. Its fun to work with, easy to sell and most of all - it gives you the Professional Edge.
