Isomark compounds cure to a very high strength and elastic polymer allowing replication and recovery from gun barrels, deep fine marks and even marks with re-entrant geometries. The compounds will also retrieve gun shot residue.

The resulting replicas are highly accurate over their entire length and minute scratch and manufacturing details are clearly visible under microscopic examination.

      ISOMARK compounds are strong and elastic enough to be pulled out of               Groove impression of the muzzle end using
      gun barrels without any loss of detail over the entire length of the replica.              F-2 Black.
