Ah yes - sorry I had forgotten about your recent surgery. There's no rush. For the record, I did once try polishing the end caps of a mains fuse after reading about it in an audio magazine. At the same time I also polished the pins of the plug. Can't say it made the slightest difference. Neither did trying out a 'Hi Fi Tuning UK Gold' 13A fuse, and since in those days I had access to liquid nitrogen, 'cryocooling' or annealing the fuse made no difference either.
As I said in a previous post, with most mechanical contacts, the effective contact area is about 15% of the actual physical contact area. I doubt if polishing a fuse will do much to reduce the surface asperities and increase the contact area, but using some form of conducting fluid to fill in the interstices might help. Would it make an audible difference? I doubt it: all you would be doing is to reduce an already low contact resistance of ~ 2 milliohm to one of about 0.3 milliohm.

I don't think it's just about resistance, the total contact users say the product reduces microarching. They believe that microarching contributes to noise, possibly even radio frequency.

You may laugh Alan, but when I listen to my system it makes me smile and its definitely improved by the contact enhancer.

Okay Martin, if you perceive an improvement that's cool.
Enjoy the music.......
Once you’ve removed the chrome and found bare copper, I don’t suppose soldering would make it sound any better. But, it would preserve that sound for a long time. And solve that issue with contact area, maximizing contact, no microarching. Was what I was thinking anyway.
What you were saying about contact enhancers, I was thinking on the rear screw in fuse holders where we can’t solder, I wonder about the silver paste? (Same thing?) They sell it at Audio Adviser, supposedly to rub on the ends of your RCA connectors, again, to maximize contact area. So, what if a dab was added to each end of the fuse? Not free, but still a cheap tweak. Just spit balling, taking it to the next level. If someone has some silver paste laying around, it may be worth a try?

What's all this "microarching" (sic)? I assume you mean 'microarcing', but how can you get a voltage gradient of 3MV/m to cause arcing between one part of the fuse end-cap and holder, when other parts of the assembly are in electrical contact, and thereby short out any voltage gradient?
If you feel the use of contact enhancer improves your system, then that is all that really matters: it's your system, your ears and your money.
