If your patches are over a year or two past manufacture, including time in distribution, sitting on the shelf at the store, and in your repair kit, it is probably time to replace them..
I never thought of that. Seems quite obvious when you say it....
Without question the patches were many years old (6-7?) , but the glue was fresh

Something to consider.
I've bent too many F&R rims to run low pressure anymore.
