Sure there are/were
If you have a Hobby Town near you, run out there and get one of each of the metallic shades in the Railroad Polly Scale line (Acrylic), plus a Black and a White and a Blue (very Dark Gray and very Light Gray will work if that shop has been "run at" getting the paints)
If they have Citadel, get a few different pots of those metallics, also
Now you have an Acrylic Metallic that dries as hard and "masking tape safe" as your White or Black paint does, with the pots for brushing stainless steel or landing gear, brake lines, etc.
As soon as you get home and try the paint out to see if you like it,,,,,that next day after you test it for "toughness", run back to that shop and pick up a few bottles of whatever colors you liked,,,,,they are OOP, and will be sold out one day soon.
If you can't find them locally, let us know, and I will post the links to the places you can browse and get some of them online.
hope this helps
