Hughes500,
They sent me a long email, a little bit convoluted. I asked about frame-less seats which they mentioned in the first sentence then went on at length to describe their process for covering seat frames and indicated in bold font that the aircraft needed US registration. Perhaps it was related to the certification docs. They did provide me with a pricing list. I did not mention that the aircraft was Canadian registered.
It is possible I misinterpreted what they were trying to say. I will give them a call on the phone to clear this up.
Thanks for the input.
