We have a customer who is looking to re-face this existing frame. It's about 230" tall x 144" wide odd shape. This was a "Big Boy" restaurant sign back in the day with polycarbonate faces. Checked pricing and availability for flex face tracking, trim and tension clips and wouldn't receive anything until almost December. Anyone have any good tips or tricks for applying a flex face to this sign? I really don't want to go back to polycarbonate for this sign. Thanks!
