Will this work on FRP paneling?

Thank you for posting your inquiry. DAP Weldwood Original Contact Cement can be used to bond most FRP to properly prepared/recommended substrates. Please be aware that this adhesive requires an application to both substrate and adherent (the two surfaces to be bonded) and that the bond if formed immediately upon contact. Because no post application adjustment can be made, it is strongly recommended that test fitting be done prior to the application of the adhesive. We also recommend that a test application (with scrap materials) be conducted prior to the actual project in order to familiarize yourself with the product and application process.
