That will be the plan.  I swapped the glass too.  I found another article on RGP about the same problem.  It was recommended to put a yardstick over the crease and weigh it down...

I sort of thought as the glass was so big, with the weight would not be isolated to the area.  So I've put a length of timber over it (just slightly wider) with weight.

Will check on it in the morning.
