Well, well over a thousand miles later and I am still none the wiser...... Actually not really, I have taken off cuts from both jobs and will do my own tests as to protecting with what and cleaning with what. The carpets I was surprised look very nice indeed, most unusual but then so are most of my clients...... Just for the record or at least mine, Shaun I wouldnt use dry fusion on anything let alone such a textile as this!!!!!!!!!!! Cheers for now, best, Dave..... P.S. no Arthur I wouldnt use a CFR machine either.....
