Hi Shai,

Scotch 206 was 1.5 mil polyester, back coated and the top of the 3M line until
the introduction of 250. 207 was the 1 mil version of 206 and, as far as I
know, was the same formulation. During the 80’s, 3M released Scotch 208, aimed
for the feature film production sound community claiming it was as reliable as
206. I till have some 208 from that era. I should check it out.

"If it ain't Scotch 206, Bake it!” was somewhat of a tongue-in-cheek statement.
However, of all the formulations that were produced, 206 seems to have been the
most stable over the years. This doesn’t mean that it should not or cannot be
baked, but I am comfortable with playing it before making that decision.
