Roofing, Could the Truck Bed Liner Coating used in Roof Repair. Not a flat roof.
I would not recommend it. The bed liner material may not be as flexible as roofing components. It is also designed to bond to metal. Applying over other components could lead to adhesion loss and early deterioration. Good luck, If this has proved helpful please remember to hit ACCEPT, otherwise I do not receive credit. Thank you.
