Not sure where to ask this so I thought I'd try here first! :) This is one for any electronics minded people.

I'm repairing an old Amiga 500 and I've had to scrape away some of the solder mask along a trace to ensure there is a good connection. There is so I can now solder a replacement socket in place. However, I feel I should protect to bare copper I've revealed along the trace. Could I just use some flux and then dab a little solder over the bare copper to coat it in solder? Thereby sealing the copper and stopping it from oxidising?

Any advice much appreciated.

Here's an image of the trace I've revealed.

 
@Vince could you help?

Thanks for the replies everyone!

@Vince Great, thanks for that. I'll add them to my seemingly never-ending list of things to get! I'll add a little solder in the meantime just so I can get this socket in place and see if it works. :)
 
@Vince Quick question! Could I ask how you apply that mask? Looking at the brand it doesn't supply any plunger or applicator? The areas I'll likely need to apply it to are tiny and as I understand it you should only be applying thin coats too.

I just slap it on with some tweezers, also use tweezers to poke a bit out... Get some on the end of tweezers, spread it about a bit... attack it with lazer for 30 seconds and job done :)

Don't bother layering it either even a big bit will go off with 30 seconds under my little lazer.
