Hi Lukas...
Sorry again to hear of the problems you've had with your K-1.
Firstly, the customer service aspects. I think Suncamera and/or the Kerrisdale shop should have told you the camera had been received back, and I do think you should have received a written report explaining the service centre's findings.
Regarding WR and the corrosion... this subject comes up every now and again on these forums, and those of every other brand that advertise weather resistance as a feature in their cameras. One of the more recent threads on PentaxForums can be read
HERE.
The thing about WR is that it's weather
resistance, and not weather / water
proofing to some recognised ISO, IP or other rating. I realise you had no such problem with your K-5, but it's a different camera used on different dates in slightly (or very) different conditions. I don't believe the K-5 is better than the K-1 for weather resistance - I think you've either been lucky with your K-5, or unlucky with your K-1. Even your K-5 may have suffered some water ingress that hasn't yet caused a problem.
Personally, I treat every camera I own as if it isn't water resistant, and I consider the WR protection to be a bonus. I never take my gear out in heavy rain... perhaps in very, very light, non-continuous rain, yes; and certainly sometimes to the coast where it may get a bit of sea-spray on it... but I never let the water stand on the camera. I carry a microfibre towel and wipe the camera and lens down frequently.
I think the K-1 is as well-protected as any camera currently available, and way better than most. No DSLR or mirrorless model, to my knowledge, is completely immune to water ingress problems. From a manufacturer or service centre's perspective, they have no way of knowing what the owner actually did with their camera to result in water damage - there are so many situations where it can happen. As a result, no manufacturer I know of actually covers water damage under warranty.
As for getting your K-1 repaired... well, as Adam pointed out earlier in the thread, it's a high-mileage camera now (even if shutter life is rated at 300,000 shots), and I think you need to consider its value. Even if it can be repaired, my guess is that would cost several hundred dollars. You may be better off putting that money towards a new K-1 (or other camera) and selling (or keeping) your existing K-1 for spares.
Going forward, I think you're wise to use a rain cover if you're going to shoot in inclement weather, so please continue to do that, whatever decision you make.
Good luck
