It will wear, but even the normal metal ramps wear over time. If you really want gold ramps, the trick is looking at options to prevent wear as long as possible. For this, you do have options. You can have them plated, then either have them clear coated or lay mylar on the ramp interior. Both of these options will eventually wear as well, but they will extend the life of your shiny gold ramps a lot longer.
My 2 cents, good luck either way
