I have painted my OGS Intelligent Position Switch to satin black a while back due to fading of the original paint job. I am repainting the OGS switch again, this time color matched to the exterior of the Prius, Winter Grey Metallic (8V1).
I have uncovered spare cans of Paint Scratch.com touch-up spray paint, clear coat, adhesion promoter, primer and several sheets of fine sand paper in the garage during a brief clean up and unpacking session and decided to put them to use.
First, I removed the OGS switch from the flying buttress console. Then I disassembled it to isolate the switch cover. I sanded the black paint as well as the original silver under-paint down until the switch was bare bone to its translucent white plastic shell using 150 grit sand papers followed by 600 grit sand papers.
The button indentation areas of the switch is harder to sand out, so a rotary tool with drum sander attachment may expedite the process. If you do use a motorized sander, you will need to be careful not to sand away the switch cover. The plastic is really thin and doesn't take much to sand off with a rotary sander. But if you are able to execute this correctly, you'll save about an hour of your time.
At this state, I washed and cleaned the switch cover of dust and debris. It took me about 1 hour 45 minutes to manually strip off most of the paint from the switch cover:
I decided to have a little fun with this project and placed a 1 inch Marvel Comics' "The Punisher" logo decal on the area of the switch cover where the palm rests, or where the original "OGS" logo used to be:
The underside of the switch cover is black with a small rectangular patch of unpainted area so the light emitted from the LED can shine through the translucent plastic and light up the original OGS logo.
This unpainted area may need to be expanded to accommodate the size of your logo. To do so, just sand off the black paint around it to accommodate the size of your custom logo. My 1" Punisher logo fits in this area perfectly with no obstruction.
I masked off the other side of the switch cover with masking tape:
After the switch cover was completely dried, I applied two light but even layer of adhesion promoter to the switch cover and allowed to air dry for 15 minutes in-between layers:
Then, I sprayed two medium layers of primer, ensuring the switch cover is evenly coated and then allowed to air dry for two hours:
At this point, you can use a 400 grit sand paper to remove the orange peel left by the primer, but I decided not to.
I then sprayed two medium layers of Winter Grey Metallic (8v1), allowing about 5 hour of air drying:
I then carefully removed the Punisher decal from the switch cover with the help of a utility knife followed by a pair of tweezers:
The edge of the logo may have slight feathering of paint. I removed excess feathuring with a micro Flathead screwdriver.
Finally, I sprayed on 2 wet layers of clear coat, allowing the project to air dry overnight:
The base coat layer must be completely dry, otherwise the clear coat will cause the base coat to run off and if you hold onto the switch cover too long, your finger print may be imprinted onto the clear coat. To be safe, allow to dry for up to 24 hours before applying clear coat.
Here is the result after two full days of patience:
Here is the custom OGS IPS switch cover illuminated:
It looks better than the original switch cover and definitely much cooler than the satin black paint job!
I feel the buttons were too sticky during initial test, so I sanded the excess clear coat from the button openings. Once smoothed down, the buttons became loose when pressed, just like how they were originally. To avoid having sticky buttons, you can elect to mask off the button openings before spraying.
The clear coat will ensure that the paint is properly protected from heavy usage. To maintain the custom painted switch, wipe the cover with disinfecting wipes once a week.
