Help - Plastic Door & Bumper Trim Removal

Hey Skodafans!

I'm wanting to respray my plastic trim on my MK2 Octavia to colour match my cars paint to make my car a little nicer to look at.

Has anybody done this?

I presume Heat Gun and Dental Floss, String or Fishing Line is used to remove the trim off the car?

Also how easy is it to remove the trim on the front bumper? Or would I need to replace the whole bumper from a VRS Octavia?

And then once it is off, use 100 Grit sandpaper to sand down the trim and then spray with, in my case Brilliant Silver paint?

See Image below on the trim I'm talking about.

I would appritiate if you guys can give some light on this, Thanks.
