Tats why i keep mine next to the hot water tank
I know it, Fortrex NQ1 was the name I think. I worked on an alternative for years.
Were you in Barrow or Motherwell Bridge.
I used to visit both.
I remember a Foreman (or something) in MB who took his dog to work. An alsation I think. I was told he used to "wash" the cover by oicking it up on the crane and dipping it in the Clyde and that he once caught the Pleasure Paddle Steamer (cant recall its name)
We had to do loads of tests including one called Explosion Bulge which involved welding a 50mm thick HY80 plate and blowing it up with 5lbs of Semtex submerged in the Firth of Forth....good boy fun........a very enjoyable time.
