> I get my greenstuff from the original manufacturer, ie Polymerics
Systems in the USA, which was recently bought by a UK company.
Do you mean Whitford worldwide? Going from the websites Polymerics
systems is a subsidary of Whitford which originated in the US. They
have an UK branch.
As to Sylmasta manufacturing putty, I remember from the mails of a
representative from them that they do not just sell putty but also do
product development. The A&B putty (their version, not the original
USA one) and those coloured putties are theirs I believe. Though I
don't know if they do the production themselves too. As to Kneadatite,
it's been a while since I checked but years ago there was another
company that told me they produced Green stuff as a licenced product
to be sold as a bulk product. Sylmasta only did the reselling (and
repacking). I've no idea what the current situation is. I'll see if I
can find out.
