I mis -understood you... I was thinking you were leaving it in it for hours literally -- a few minutes is ok. I haven`t ever had that issue mrjoejohn -- many years back I had a little of it on an all -poly system but it was caused really I think from sleeping with it on and I used to use styling products too.Have never had it on any Toplace systems but then I only use a light bond,
as you know, and a poly perimeter on which I only put a few little strips of tape and de-bond it nightly -- am really interested to hear if anyone else has had that issue and did they realise what caused it ? Very `odd`. Paul.
