I'm not sure you got the point, The spoiler is made of rubber. Paint
it with a spray can and then let some unsuspecting tool (my neighnor for
example) lean on it for ya and then look at the pretty design the stress
cracks made. The bumpers are a different story though. Go crazy with a can
of Duplicolor on them. I'm a regular 'ol Earl Scheib with a rattle can.
See ya,
Sean.
