Weldwood turns hard and brittle after time. The contact cements designed for leather stay flexible - longer.
Weldwood, the Gel Formula, IS a contact cement.
Like Sandy I've been using Weldwood for a long time - 35 years or longer - and never had that problem on leather?? and I've used it frequently on flexible items such as clothing or lined bags over that time and have never experienced brittleness - other's mileage will vary of course......I'd be real curious on how long it's taken for you to experience that brittleness???Weldwood turns hard and brittle after time.
