I should know the answer to this ?

I don't want to should uneducated but what is the difference between "resin and styrene"

Is there an advantage to using resin or is it that the average guy can replicate using resin, where as most of us don't have the capability of injecting styrene?

Resin and styrene are two completely different things.

A styrene kit is made by injecting melted styrene plastic under pressure into a mold, allowing the plastic to cool and solidify, and then popping the parts out of the mold.

Resin parts are made by pouring liquid resin into a mold (just pouring it, not injecting it under pressure), and letting it harden before removing it from the mold. As far as resin goes, most of the time the "master" used to create the mold is a modified existing styrene body or kit part.

The main difference between the two as far as model kits and parts are concerned is that injection molding is a process designed for high-volume production, while resin casting can be done by anybody, on a "one at a time" basis, without the need for expensive machinery.

The relative ease and inexpensiveness of resin casting is why the aftermarket companies use that process instead of the injection-molding process, which requires mega-buck injection molding machines and expensive steel molds.

That's about what i was thinking. Thanks for the response.
