Most manufacturers or resin kits use a mould release
agent to allow the resin castings to release better from the rubber mould.
This decreases breakage of parts, and greatly increases the number of parts that may be
made from a mould. Both of these factors help to keep costs significantly lower.
Mould release does, however, prevent paint from adhering well
to the parts. For this reason, castings must be cleaned to remove the mould
release agent. Soap and water alone will not remove most release
agents.
The best product to remove our release agent is our own ResinPrep,
available only through our dealers. Floquil's Diosol will also remove our mould
release agent, but please be sure to read the safety precautions and warnings on the
label.
Both of these products should be successful in removing other
manufacturer's mould release agents from their kit parts, but please check with the
manufacturer.
Pour a small amount of ResinPrep in a glass or non-styrene container,
and then carefully and gently scrub all castings. A soft toothbrush works well for
cleaning larger parts. Tiny parts may be allowed to soak in the cleaner for a brief
time.
Do not clean any styrene parts that may be included with the
kit, such as strip styrene, Tichy steps, ladders, and other Tichy or Grandt Line parts.
ResinPrep or DioSol will dissolve styrene.
Using a container in which to clean the kit parts reduces the amount of
cleaner required, as well as lessening the chances of losing a part down the drain.
After all parts have been cleaned with the ResinPrep, carefully rinse
the parts with lukewarm (not hot) water. A sieve is great to hold
tiny parts so they are not rinsed away. The ResinPrep will turn a milky colour when
it comes in contact with water. Ensure all parts are well rinsed, and allow to air
dry.
