Help with aquafade touch up

[claret badger]

I have a '94 Yo Eddy aquafade which I believe has the original paint. It has battlescars which I would like to touch up to avoid rust issues etc. but dont know the paint codes or what paint to use.

I dont want a respray hence going down this route!

The paint after a good clean up is also a bit flat. I was thinking of car wax to shine it up, or should I put a coat of lacquer over it?

Any help much appreciated :-)

Thanks
