remember the hole in the ozone layer caused by those cfc's. What happened, did it close up? that's great ,put down your sun block.It,s probably no coincidence that Duponts 25 year world wide patent on cfc was running out. lucky for us they came out with a NEW cfc that doesn't hurt the ozone layer ( I think ) . What, a new 25 year world wide patent. great news
If you ask they can say no. If you just do it, all you have to do is apologise and move it , at some time in the future. I'm sorry I didn't know , works. bw
