I've been picking up old stereo equipment from the '70s and '80s at garage and estate sales, and I've finally pieced together a pretty nice old-school stereo system. I've been cleaning up the components, but I'm having a hard time with some of the old plastic knobs: they're faded, white, and look super gnarly now that I've dusted and wiped down the rest of the plastic and metal.
Can I paint these knobs with something that will cover them well? -Andy
With the right primer, you can paint anything. But I just saw this tip from Lifehacker on using Vasoline to make old plastic gleam.
Has anyone had other experiences with improving the look of dried-out plastics?
