Thank you this is really helpful, fundamentally it will get rained on so might need a different solution.

Could be wrong, but pretty sure the person above means that the problem is rain/moisture too soon after it is applied. Not rain/moisture in general. The product needs to remain dry until it’s fully cured, otherwise the excess moisture will cause it to stay malleable/messy.
