Buffing out scratches in an acrylic tank

[Enigma]

Another Chilliwack girl! I was mostly raised there.

What about the 3M headlight kit?

I have a friend who used this kit on her truck . . . her plastic lenses came out looking brand new, and it was really easy (so she says). I'm just not sure if they could be used on acrylic, or what the difference would be between acrylic and plastic.
