If it's metal of some sort, you can produce a mirror finish by following these steps.

• Step 1: Wet sand using 1000-2000 grit sand paper
  
• Step 2: Apply Blue Magic Metal Polish (or similar)
  
• Step 3: Apply several light coats of clear paint
  
  Notes:
  
  
• Step 1 is optional if the surface is in good condition (but will require more work in step 2)
  
• Step 2 will go a lot faster if you use a dremel / drill / grinder with a polishing wheel
  
• Step 3 is optional if you don't mind repolishing at a later date
  
• All the products should be available at your local auto parts store (Advance Auto, AutoZone, etc.).

It's almost impossible to remove a sticker after it's been sprayed with clearcoat from a small spraypaint can like this that can easily be carried in a backpack: https://www.amazon.com/dp/B00407NK6A/?tag=car-bibles-20

The same for sharpie. Can't ever wipe it away.

Lets hope no one ever does this...

It would be a tragedy...

Personally OP, I would have gone for a higher quality clear coat on top. The red is vivid and nice, but the texture on it looks less than wonderful. I would have used Duplicolor Gloss spray paint from experience.

Odd, but either automotive or urethane should work, like this duplicolor acrylic laquer
