Don't know, probably this didn't happen later on...?
It wasn't really bad seals. What it was is those are V-seals and I found two of them came twisted 90deg in their groove, which would NOT keep the water out - if submerged or pressure-washed...
I was able to fix that and actually re-use the same V-seal - since it was only slightly deformed.
I still think (or should say hope...) that the Brazilians did double-check that particular matter, in later batches. I also know that to be safe, John (Jatonka) had inspected the ones he had in stock, at that time - and found nothing wrong.
