As probably previously mentioned, some time ago I made an effort to get some touch-up paint for the numerous dings the Fuji's endured throughout its lifetime.
While the staff at the automotive paint place couldn't get an exact match since their gear required a relatively large, flat panel, they did spend a commentable time bothering my frame with an LED light and mind-boggling array of colour swatches. Of course I was never far away and concurred with their best - if-inevitably-not-perfect - match.
Several months and a tenner for a fairly generous pot of paint later I found myself pressed to get the job done before the cold, damp seasonal misery took hold.
To begin the bike was thrown in my newly-acquired Park workstand, wheels removed and washed as best as possible. Affected areas were treated as nec. with phosphoric acid to kill any rust then degreased with isopropanol before paint was applied... given the paint's unsurprisingly propensity to yield to the demands of gravity, I tried to treat "upper" surfaces, then leave them to flash off for 20 minutes before rotating the frame in the stand and touching up the next set of horizontal surfaces.

Once I'd done all that was viable in the stand, the frame assy was laid flat on the kitchen table, damage treated on one side, left for a bit then flipped and repeated.
Predictably neither the colour match, nor the physical execution of the paint were perfect; however I went into this venture eyes-open - aware that the primary goal was to protect the underlying steel; that secondary being to make the bike look less like it'd suffered an hour in a tumble drier full of nuts and bolts..
My intention was to take before and after shots of the affected areas; however sadly the reality fell somewhat short.... so here's a half-arsed mix of what I managed to document. Apologies for the lack of consistency but I was concentrating more on just getting the job done.
Wear at the chanstay from where the rear wheel had apparently repeatedly come loose and rubbed the paint through to bare metal.. I was keen to get this treated as I suspect this area's fairly highly stressed and a rusty hole wouldn't help!

By far the worst bit of damage was on the underside of the chainstays where some ham-fisted bellend had lashed on an ill-fitting stand in the past

I'd protected this area with wax before, so got that off with a hair dryer and rag, before the usual prep treatment. I'd planned to use primer but in the end figured this might be too messy / too high-build so the paint just went straight onto the bare metal..
This bit was pretty easy to do with the fat integral brush that came with the pot, given its size and while far from perfect that wasn't really an expectation. The colour match is reasonable and it appears well-sealed.. if I could really be bothered I could build it higher and flat it back, but I think that's probably unlikely.

The other major bit of damage was long rub along the outside of one of the chainstays..

I went in fairly intricately at first, just covering the bare metal..

.. then slapped on a wider, longer second coat to ensure it was all sealed and encompass the bit to the rear I'd missed..

Again no oil painting but it should prevent any further rust and looks tidier than it did from a few feet.
I also touched up many other smaller areas on cable adjustor and bottle mount bosses, plus many other random chips and the area where the failed gear cable had abraded the paint on the downtube. For some areas I used a sharpened matchstick to apply the paint and the quality of application varies significantly; with some large blobs in some areas, while in others the paint has sink beneath the level of the existing stuff.
Amonst other niggly little things I had to remove one washer from between the rear mudguard and chainstay bridge to allow comfortable removal and refitment of the wheel, now that the tyre actually has an appropriate amount of air in it. The washers were originally fitted to give clearance between the FD and guard, so I couldn't go too mad removing them..
I also found that my pannier bags have been heavily rubbing the rack and taking it right the way through the powder coat in places. While a bit irratating it's not the end of the world as the rack's a bit tatty anyway.

I do need to sort out some means of protecting it however; would be a prime candidate for some brass plates as per the Brompton, however I don't think I have the patience and resolve to commit the necessary time given the amount I'd need; although since it's round I wonder if I could knock some up by slitting some thin-wall 10mm ID brass tube..?
Finally as per my other thread I checked the chain for wear against a new one; coming in at 1.9mm elongation over 55 link pairs for around 0.14% wear at 1390 miles covered and giving a projected life to 0.5% wear is c. 5500 miles..
That's all for now - the bike is currently still sans-wheels, up-ended on the dining room floor to give the paint the best chance to harden fully in the warm and dry.
Will re-assess later in the week as to whether I want to try and improve the paint, while really it could probably do with another wash (I did a crap job) and wax since it's been degreased in places and winter's on the way..
