Nice touting bike and the only thing I would change is to get that innertube promptly off of the rear fender. I might move the headlight from the front luggage rack to the front wheel rack.

lol - thanks, and as you might notice eight pages and many months have elapsed since that first image of the bike as I got it; I guess now's as good a time as any to showcase its progress:

Doesn't look much different really, does it?
That's a great bike. You could cycle round the world on that.
It's a big from me.
Why not just touch up underneath in grey primer for the time being, better than leaving it exposed.
Rightly or wrongly, I seem to recall from my time playing with cars that many primers are permeable / hygroscopic, so could potentially make the situation worse..
Of course I'm overthinking itYou’re overthinking it, must be better than bare metal
After decades of using a pair of double ended multiple sized stubby cone spanners (stepped 13/14/17mm one end, 15/16mm the other) not dissimilar to the Park Tools DCW series, I, on a whim, ordered a pair of cheap but "proper" (long gripped handle, single size) cone spanners in 13mm and 15mm from Wiggle. I even bought a 15mm pedal spanner at the same time which is identical but with a longer handle (just in case I might have been tempted to use the cone spanner on a stubborn pedal and chew it up). Only a few quid and I haven't regretted it - I certainly am glad of them when re-greasing my hub bearings. They do the job, offering greater comfort and ease of use than the stubbies.
Of course I'm overthinking it
A quick tickling of Google suggests you might be right and that I was either mistaken / taken in by an urban myth / looking at something for a specific product. Time to start looking at primers then, I guess!
Today the postie delivered my new cassette; purchased as a replacement for the existing one due to the chain skipping constantly on the 11t sprocket.
As much as I generally hate everything in the world, I was again impressed by Shimano's newer-style packaging - both in terms of its minimalist aesthetic and apparent sustainability credentials; looking both recycled and largely recycleable; with minimal, "look at our website" instructions

The bike was recovered from the shed, inverted, chain split, brakes disengaged (6 turns on the still-novelly-lovely Avid inline adjustors allowing the noodle to be released from its bracket) and wheel removed.
I was struck by how "Early Learning Centre" some of my tools looked in their bright, contrasting primary colours - which is probably appropriate for my level of expertise..

The cassette was quickly off and I decided to compare old and new before fitting the replacement - the coloration on the old one (LHS) is the moly-impregnated wax I run on the chain:

I was slightly disappointed to find that the largest seven sprockets are effectively rivetted together; reducing the liklihood of being able to replace individual sprockets as they wear. The smallest two sprockets however are free, so I took the opportunity to compare old and new; with surprisingly little obvious difference:

Investigating further revealed a lot of apparently very moly-heavy wax packed into the spaces between the teeth and the recess behind them on the used sprocket:

I think we can all see where this is going... I cleaned off the chunks of accumulated wax from this most affected sprocket with a wooden pick and toothbrush, while the rest of the cassette was chucked in the oven for a bit on a low heat then cleaned with a cloth and toothbrush:

Evidently it seems that the wax has been accumulating on the cassette (especially the smallest 11t sprocket), lifting the chain our of the channels between the teeth and causing it to skip.
I was slightly concerned that this might have caused excessive wear to the sprocket and there are some burrs present on some teeth; however while burrs are present on the drive-faces there are also some in areas that the chain rollers would never contact (such as the top of the tooth to the right of that labelled "NC" in the image of the 11t sprocket above) so I think these are from manufacture rather than use. Besides, it'd probably take a lot more force than I can exert to plastically deform that teeth in these areas..
All back together again and I went out for a quick blast round the village; the cassette performing flawlessly (at least from a skipping perspective) despite grinding up a short hill as best I could in the highest gear. Previously it'd skip repeatedly at high cadence and minimal load on the flat..
As much as I love it, it appears the wax is to blame. This seems slightly odd as I'd covered about 700 miles on this bike before this problem occurred; while my Genesis has done 4.5k miles without any similar occurrances. I think it has to be down to one or both of two factors:
Wax consistency: I've recently added more paraffin oil to the mix in an effort to make the wax softer / less brittle, stick better and hence give more corrosion resistance. Maybe this is causing the buildup.
Excessive waxing: The chain on the fuji seems to have an irritating squeak; which I've tried unsuccessfully to sort with repeated re-waxings. This means the chain's been waxed far more regularly than the usual 300-350 mile intervals; potentially causing more buildup.
In addition it seems that the deposits on the sprocket were very moly-heavy; suggesting that the wax had been forced from between the chain and sprocket under load but the moly and the lesser amount of remaining wax had compacted down to form something far more compression-resistant that wax alone.
Since I like the idea of the softer wax from an adherance perspective I think I'll split the existing wax cake in the pan in half and add the same mass again of raw wax / oil mix to cut the moly content in two. I could also pull the chain from the pan at a higher temp during waxing; meaning the wax is more mobile and less likely to accumulate so much on the outside of the chain (which I suspect is where most of the excess on the cassette has come from).
I've not had enough time on the bike to see if the shifting has been affected, but I guess it's not outside the bounds of reason that the ghost-shifting I was experiencing might also be down to excessive wax on the cassette. I think I might have cleaned and waxed it before riding it a much, so I can't say whether it was present beforehand or not.. chances are the issue probably remains as the chain's had maybe 4-5 waxes in the time I've had the bike and it would obviously take a while for the wax to buildup.
I also eyeballed the RD / hanger while the wheel was off, and if anything it seems kinked outwards at the bottom (i.e the opposite way you'd expect it to bend if dropped on the drive side). Yes, for the fifteenth time I need to pull my finger out and make an alignment tool..
Ultimately today's escapade has been no big deal providing no damage has been done; I've learned something while the modest money spent on the new cassette's not wasted as I'd intended to get one in the bank anyway.. so that can go in the spares box.
In other news I took a better shot of some of the wear on the rear tyre - definitely needs replacing but I reckon I'll get a few more miles out of it yet while I fanny about trying to sort another; which is good as I'm still waiting on a supplier to answer some questions about potential replacements..

It would have been quite nice to have got out for a waft today; however I'm feeling somewhat sub-human again and I'm less keen on the sporadic spring rain currently happening outside.. so maybe I'll just stay inside and drink beer instead.
EDIT: Got out after all; bike behaved itself and the skipping issue seems sorted
