Thank you, you've inspired me! I just purchased a silver plating kit from Amazon and I'm taking inventory of all of the contacts and springs that I want to plate. I bought a spare brass GPin and later had regrets about not getting the LUX version, so I think this will be the first thing that I try. I was also flirting with getting a gold plating kit, but I'll take it one step at a time.
Kudos, Man that's some DIY dedication.
When I say "When to plate" there is a precious metals plating Co I use for work occasionally. Kinda snuck them in on a job where we were under on the shop minimum
I'm not sure on the exact plating thickness but there is not a lot of room on the GPin body and collar. I defiantly would not go more than ~ 300 micro inches for external GPin parts.
On the bottom contact there is plenty of room.
Yeah gold (or gold alloys) are kinda tricky; from what I understand your gonna have to flash with nickle first on SS parts.
Sounds like a fun project
MY
mods came

but now I'm short on atty's

. So I'm offing my ELA to get somethings that'll compliment my new GP additions.
