">>>><BR><BR>Hello Paul,<BR>When you have heated the =

<DIV> I suppose Wynne's Pry and Dry is a British =
product and
we can't get it here in the U.S. Anybody know an equivalent =
product we
can get stateside? I need something for those frozen let-off =
screws in
old pianos. I've tried heating. They still break. =
I've tried
Protek. They still break. </DIV>
