Proper methods for caring for neo-prine covers

Well I've got some neo-prine covers for my lens, however I've a slight problem that needs addressing. When put in the bag it can often end up getting rumpled at the edges where the bag sides catch and pull. The result is that some starts to get bent sections - these seem to dull down to normal somewhat when pressed, but still show the bend. So I was wondering if there is any good way to either:

a) Restore after bending

b) Help prevent bending when putting into the bag.

Ask Lens Coat. They do tons of neoprene covers for bodies, lenses, tripod legs..etc.
