Thanks for the comments. As mentioned both Lionel and Fine Arts were of no help today. Fine Arts suggested using silicone flashing from a window shop, it must be thin they said. I have also called an old source that Lionel had given me years ago. The name I had was
Bill Zabo
136 Pershing Ave
Carteret NJ 07008
His phone no longer works but the internet says he still lives there. I will write him a note over the next several days. If anyone else knows him let us knows. I will let you all know if I learn anything. Thanks
