I've never used resin tracks before and I followed the instructions that say immerse in very hot water and bend around the sprocket. I've done this and held it in place while it cooled but it then still springs out and looks awful.

Is boiling water out of a kettle hot enough?
Also because the track lengths are so short I have glued them together before bending and the joints keep breaking as they bend.

Is there an easier way of working with resin tracks?
Any help will be gratefully received.
Cheers
David
