Dear Khun Sanjay,
Thank you for your kind information.
For the ultrasonic testing issue, we regret to inform you that this will be excluded from our inspection scope as testing FRP surface with this method an “error value” will be displayed. Moreover based on our long-term experiences in FRP industry, we would like to confirm you that our offered methods are sufficient, and they are also widely used for FRP inspection.
Hope our explanation is acceptable. And we highly hope to get your purchase order soon.
