How plasti-set works to repair small plastic parts:
Use the reusable molding block to create a mold of your missing lug or part.
Then use the powder and the liquid to recreate your missing piece.
In the video below Ken uses plasti-set to create a mold from an original plastic part off a pin ball machine. He then uses that mold to create a new part for the machine. Watch the video below to see how it works.
