Dying plastic

Can’t stand the white plastic on my bike. Going to dye the radiator louvers, gas tank, and air box, “Graphyte”. 

Ordered 3-7oz bottles of Rit dymore, and some 400 grit. 

Suggestions and/or guidance appreciated.

Looked into it a bit but couldn't really see the results being something I liked. However, I always like DIY so let us know how it goes for you. Best!

You cant really paint a tank properly as far as i know, cause it breathes and the gas vapors will bubble the paint. Plastic kits and decals are so cheap and last much better for MX bikes so I personally wouldn't bother.

But if you enjoy the process, why not. I would skip the tank though

It’s not paint, it’s dye. 

If any of this was “available” I’d be buying it. 😎

It will likely only stain the surface, but let us now how it goes.

It’s definitely looking like a science experiment. Anything is better than the ugly ass white. It just doesn’t mix well with Texas Red Dirt.

Dyeing a plastic motorcycle gas tank (like a white or natural translucent off-road tank) with C_4474741501266275961%7CPROD_PC_4474741501266275961&q=product&sa=X&ved=2ahUKEwiSwdn4k-SWAxVxkmoFHe0ZIzMQxa4PegoIAggACAAICxAC" id="pvlinkkrWiapKwLfGkqtsP7bOMmQM_1" rel="nofollow">Rit DyeMore(synthetic) works for polyethylene/polypropylene plastics, unlike paint which bubbles from fuel vapor, though results can be unpredictable (e.g., black turning purple). [1, 2, 3, 4]

 
Process & Reality Check
  • Works on: Translucent/white polyethylene off-road/dirt bike tanks (Acerbis, IMS, etc.). Metal tanks cannot be dyed with Rit.”

They say to let it flow inside the tank also. Impervious to fuel evidently. 

Like you, I’m finding the entire thing a bit hard to believe.

I've dyed a few parts with rit dye, it does work and seems to hold up good, would love to do a full set of plastics one day.   The dye did start to fade after a while, but not terrible, but that was probably my piss poor dye job.

Time to get to sanding. UPS dropped this off about 10 pm last night (WTF really?).

Unless its aluminum, then pick a color.

Second dunk on the tank. Evidently patience is my friend.
