When I reprooofed the fabric (canvas?) hood with Renovo on my first Morgan it appeared to shrink slightly Richard!
That's interesting Graham, when I treated my Neverflex on the 4/4 Sport it certainly relaxed the material and it was easier to put up.
Ironically warm weather eases the situation in a big way on the Neverflex.
I guess this will have been discussed on the various Lotus forums Heinz.
