Dash pad... Paint or Dye????

I can say first hand the shop I worked at had to dye an airbag for a 300c, it ended up pealing and it was done at a professional shop.

Although I dont know if paint would work either, never tried it, I suppose if you used a scuffing agent(scuff paste) and a toothbrush(to get the stuff into cracks and hard to reach areas). it might work.

good luck
