  Correct. They call it splatter paint or something like that. It has lumps
in it and you spray it on that way. I guess the size of the lumps control
the size of the bumps in the finish. I used to work in a paint and body
shop and we used the stuff to re-pain the insides of trunks of 60s and 70s
cars that had that finish. The stuff they used left a greyish finish with
large spots and streaks of very dark color.

   You can sandblast or bead plastic the base material (metal or plastic)
and then paint over it and get a rough finish but it will have holes and
dips in it instead of bumps (pebbles) so it's not the same.

   I've never seen any of that stuff close up. What's the liguid mitrogen for?
