Ever had the chance to test out just how good the WR is ?
But I'm well trained now when out with my wife, and always make a conscious effort to remember to put the baby's rain jacket on BEFORE scrambling to put the camera away .... Not doing it in that order risks putting the K7s magnesium alloy body to the test rather than the WR !

I recently bought an AF-540FGZ II 'AW' flash, the ideal pairing for the weather resistant camera ..... On the 3rd page of the manual is the instruction ....'Di not expose the flash unit to water or moisture as there is danger of electric shock' ...!?!?

Not had a single problem. Not one.
This gentleman has had no problems either apparently ... https://www.youtube.com/watch?v=Eo61t5fH6Qw

All my weather resistance cameras and lenses - K10D, K5, K3, K30 and my three DA*series lenses have been out in all sorts of weather, some of it torrential rain and blizzards. I've never experienced the slightest problem, other than trying to keep the front element dry so the image isn't blurred with rain drops.

I probably visit some of the areas David does, I live in Northumberland, and go on trips to North Yorkshire and Durham. If I had to worry about the weather I d not get out half the time

I've had no problems with weather resistance, although a friend of mine did have a problem with a waterproof WG-3. It leaked.
I suppose there's always the potential for something to go wrong and as lenses get older seals may need replacing, but it's all good so far.
Best regards, John

Used my K7 than KS2 in high humidity/dust storms with no issues either. Repeatedly. I do always take care to either let dry or vacuum/wipe dust off all my equipment once I'm home and store it in dry, well ventilated places. Don't know how much of a factor that is.
Toughest little bugger in my collection is the K100D Super - with no WR and more visible sand on and in it than an average desert. It doesn't stop it taking photos

Have a feeling this thing will go on long after every other camera I own dies....

The biggest problem I had was keeping water droplets off my ND Grad filter, which proved next to impossible.

Some cameras, some lenses, some bits 'n' bobs
A manic disassembly & drying session followed - the battery needed recharging but after a few days all worked as it should. I eventually sold on the K7, but am still using the 18-55 - after removing the water-marks from each lens group.

Over Christmas in Morar, NW Highlands I went out to Camusdarach beach for a walk. It was blowing a severe gale, really strong, so whipped up a bit of a sand storm from the dunes, then a hail storm followed by torrential rain. I had a K-S2 and 18-135 with me - no cover or bag, and although the downpour did wash off much of the sand, it got into all these little spaces between elements of the camera and lens. Put it under the kitchen tap when I got back home and gave it a good rinse until it was clean, dried it off with a kitchen towel.
Later that night took it out for a lovely west coast sunset - the foretelling of a glorious Christmas day, blue skies and very calm.
Some of the photos are less than perfect with the combination of hail/water/sand on the glass, but the camera and lens? Never missed a beat.
K-5, K-3 II and */WR lenses all holding up well too. This is one of many reasons I choose to stick with Pentax.
K5, K200 and several film Pentax cameras!

On the two Pentax K3 variations; I've used them in most every type of weather, have never had a single failure. The grip seems to hold up equally as well, just as long as one does not remove the grip or attempt to change out the batteries before ensuring the devices are not wet (at all) or dirty. All of the Pentax aw flashed have the same exact level of resistance that the camera bodies with the aw designation do.
As for the lenses; I've been through all of them with the exception of the 560; again zero issues relating to the wr resistance.
In testing out the wr resistance the cameras and accessories have been to all sorts of extremes such as: Prolonger use in the cold (severe cold - far exceeding the manual specifications) in places such as Antarctica, Alaska, and the like. All of the hardware holds just fine; autofocus rarely gets a bit slower (but very trivially), manual focus also a bit slower, and zoom settings as well. But all still functions perfectly.
For the other extreme in temperature... Easily able to sustain forty degrees Celsius with one hundred percent hundred percent humidity, and even under direct sunlight. Could go further, but I haven't for prolonged use. Still would not suggest ever leaving higher end equipment in places such as a vehicle on a hot day.
Then there's dust, dirt, sand, etc... From dirt at construction sites, to equestrian events, to beach events. Have never had an issue.
Moisture and water resistance... I regularly expose my gear to salt water spray - zero effects. As for levels of items such as rain... I prefer not to use gear in sustained heavy downpour of rain, but the wr gear has received a thorough rain testing on more than a few occasions. for heavier rain would still suggest some sort of professional cover.
Still wishing that there could be a type of IP rating though.
