How different are resin model material than those plastic 1/350 scale one's? Is it easier to cut, paint, and put together?
Resin is solid. So when you see the upper deck of this ship for example:
You see it is a solid piece.
Injected molded plastic is not. It is just a thin layers of plastic molded appropriately like so (on another ship) that you glue together:
It is also different material.
You use plastic cement for injected modled plastc, and you use different types of glue for resin, like Quick Grip Permanent Adhesive or sometimes glues that you mix, one as an e[oxy and the other as a hardener.
Resin is heavier, and sometimes you will have to use saws or dremel tools to work with it.
Generally most of the major details are molded directly tino the resin, where as a plastic model has a bunch of small platic pieces you glue on. The smaller details, like the handrails, sensrs, etc. come in those photo etch metal pieces you see for both models.
Anyhow...those are some of the differences.
