Glitter paint was popular in the seventies, especially for low-riders. It might be considered a bit cheesy these days, but I'll bet you can still get it. As for glow paint that can be switch on and off, can it really be done at a reasonable price? How?

It is not so much a paint, but EL sheet decals you can fit to almost any surface. It is technically possible to make those.

You could also use a UV active paint, and black light tubes to illuminate it.

im just trying to create the next trend like spinners rims ect.i was thinking like black or white paint with alot of glitter and as for glowing paint it can be affordable but its just an extra feature you add to your car like a body kit its up to you if you want to pay for but one thing for shure your car will stand out at night
