i got to ask

[LowRam]

Ive never heard of Plasti-dip until i got on this site can anyone explain to me what this is? is it like a spray on paint type of stuff or what?

seem alot of people use it does it hold up on interior peices?
think someone even did there wheels did that hold up?

im just curious how its applied, what all it can be used on and how well it will hold up and last. everyone makes it sound like great stuff
