Not sure about any stores in that general area (sorry)
Most of the
WWX models are resin, but some are in HIPS plastic (same as the
GW plastic). As for the resin, it is superb and typically very well cast. Of the hundreds I own from this line I have found very few models with bubbles that need filled, and most models have little to no mold lines, either. I have only ever had one miscast that needed to be sent back, which was promptly replaced.
These are the first resin models I have gotten myself, and they definitely need to be treated differently than other mediums. You can find plenty of guides online about working with resin miniatures, but here are some general tings to keep in mind:
1. Resins are potentially dangerous. You don't want to be breathing any resin dust or working on the models near the kitchen or food items, etc. Some people wear dust masks when working with resin, some don't (I do). I tend to wear a hobby apron to keep resin shavings off my clothes, but that's just me.
2. You need to wash the miniatures before doing anything else with them. Any mold release still present on the casting can potentially cause glue and/or paint to not adhere to the model. Warm water mixed with a little dish detergent works well. I use a bowl of this mix to wash the models right on the sprue, gently scrubbing each all over with a cheap soft toothbrush (that's only used for this purpose, of course!). Then I give them a quick rinse in a bowl of fresh water. Let the models air dry completely; I use a dedicated dish-drying mat for this.
3. When removing bits from the sprues, be careful as resin can be brittle. Using clippers or blades too aggressively can result in bits snapping apart (happened to me a few times). In particular, removing the feet from the sprue can cause the legs to snap at the ankles, which is fixable but annoying. To help avoid this, I started using a small razor saw to remove the models from the sprue at the feet, and now no broken ankles,
lol.
4. Use a blade to remove any mold lines, being careful not to remove any of the fine detail. I recommend that you do NOT file or sand any of the resin. You do not want that dust in your eyes or lungs, or even floating in the air waiting to be inhaled by someone else (or a pet).
5. You can use just about any good hobby super glue to assemble the models. You may find that some parts do better with pinning, but for
WWX I tend to just pin one of the feet to the base so that it has a good connection. A few of the models do have some delicate connection points, but there are various ways to deal with that. For certain delicate joins I enhanced the gluing by adding a little liquid green stuff (or a dab of regular green stuff) though that was probably only needed because I was using really old dollar-store glue.
Keep in mind I am a rather finicky miniature assembler/painter. A lot of guys don't even wash their
WWX models, and just slap them together with little prep at all.
Not sure where you have been looking online for info on
WWX, but one of the best places to visit is a
FB page called the Dark Council:

You can find plenty of advice and pictures there, and the guys are very helpful.
