You put them on and ride. Road spray and direct rain? Panniers are subjected to the same.
Perhaps I should rephrase as: 'it would not be straightforward to get custom-made covers made in Colombia at fairly short notice that could be relied upon'. The issue is not the waterproofness necessarily but the fit, which is obviously not an issue for panniers themselves. The fabric of any cover would likely also be thinner and therefore more prone to getting torn. But glad that it worked for you!
