Colour Coding

Take a look at any smart and you will soon notice things that don't quite match.

I Don't Get it, What Is Wrong?

If you have a black tridion on your smart you won't have much of a problem.
Silver tridions however still get accessorised with black plastic parts.

What Parts Are Black?

  • Front lower splitter on the facelift and cabrio models
  • Side skirts
  • Fuel filler cap
  • Air intake
  • Exhaust valance
  • Door handles
  • Wing mirror bases
  • Roof spoiler
  • Mirrors and the grill can also be black despite the silver tridion

    Painting These Parts

    It isn't necessary to paint absolutely every bit of black plastic, the main ones will do.
    I started colour coding Kat's Fortwo Passion, being a passion it had a silver tridion.

    You could pick up a can of spray and do it yourself, chances are it will look rubbish,
    the paint will look patchy and will stone chip easily and flake off in weeks.

    Your best options are:

  • Take the parts to a spray shop
  • Take the car to the spray shop

Buy the parts already sprayed

Kat's Fortwo - Stage One

In this instance I chose to buy the two parts presprayed from
Nipper20y on Ebay.
The fuel cap was new and the painting was very good quality, the valance was used and had just been removed from a car, again the painting was good but had slight imperfections
It was perfectly acceptable for a used item and the imperfections had been pointed out.

As you can see, this quick bit of colour coding has helped a lot.
Stange two will be either the side skirts or the front splitter.


Colour coding is a far more popular mod on the Roadster.

If you have a silver tridion Roadster and have before and after pictures of black parts 
becoming silver I would be grateful if you could send them to me to be published here.
