Step 1: Getting Started
1) A 2 piece plastic skin or shell for the model of phone that you have (unless you choose to case mod the actual phone), mine ran me ~$10.00
2) Spray Paint - (1) can of flat black and (1) can of gold
3) Steel wool or fine (600) grit sandpaper
4) a 3/32" drill bit*
5) 3/8" power drill*
*Optional, only needed if you intend to drill the flip cover shell for that added touch.
Step 2: Painting the Parts
If you really want to go all out, you can drill the flip cover piece with a series of holes (to give it a more authentic "grill" look). I drill a few holes in mine using the flip cover of my replica communicator as a template to get the pattern of the holes correct.
To just get the basic Communicator look, the base cover piece, for the the phones keypad section, will be painted black. The piece that attachs to the flip cover/screen will be painted gold.
Follow the instructions on the brand of paint that you buy for painting and drying time.
