I noted everything I did to the Atari over on my album (1st link below) via Flickr. Photo #2 explains everything in detail.
For the trim, I basically taped (2) craft foam sheets together and placed a layer of paint (mixed colors) and gently pressed the faceplate onto the paint. Painters tape is optional (see photo in album) I mixed Bright Orange or Cadmium Orange Hue and Burnt Umber, which I covered the entire craft foam sheets with. At first it was just White or Titanium White (2nd photo at the 2nd link below), but I noticed it made the Orange much lighter, but I needed it darker. I did not use White for this project. All the paint is Acrylic,which you might be able to find it at your local Dollar Tree, Dollar General, or Dollar Store. I wasn't able to. I purchased mine at Hobby Hobby (paint's called The Fine Touch, $2.99 per color), which they should have the colors mentioned above in the paint section.
Click the large arrow on the 'right' of each image for the next 4 photos to see the entire procedure for the trim. I would recommend to anyone not to blob the paint on or in thick layers. A good layer or two will do the job, if not, you can apply more paint onto the craft foam sheets.
PS I noted all the supplies as well.
