is it really spalling or could it be weathering or ASR or poor aggregate quality or damage from snow plows or road salt or something else? I would not expect spalling to be a big issue for a gutter. you need to do some investigation to determine the problem first. CTL or somebody like them could help with the testing and identification of the problem

Take it with a grain of .... salt.
It also may have to do with the amount of freeze / thaw that the surface saw.
