Hello Dice Duke, I am sorry to know of the difficulties you are finding in working on the models.
We have recently published a video about Warlord resin that explain a bit more about the material and provide also some hints on how to clean it.
If this could be useful to you, it is here: YouTube link
At least as far as I know, this kind of material is very new for the world of miniature gaming, which is already very polarized between the supporters of metal, plastic and resin… and indeed it is different from metal, from hard plastic and for the more traditional resin that we may be more familiar with (that we already sue for our some of our range of vehicles or Cruel Seas ships).
There are several characteristic of this material that some gamer can find revolutionary and a blessing, like the light weight and its flexibility, while others require more time to get used to… and this I believe, is the cleaning of the mould lines.
I work for Warlord, but I have no problems to tell you that it is more difficult to clean Warlord Resin in some cases than hard plastic and metal.
This is not always so, but in the areas where you would find very difficult to clean metal mould lines (faces or very textured surfaces), you may have a harder time with Warlord Resin, at least until you get used to used to it.
This is a less forgivable material for our quality checks compared to metal and also requires us to keep improving the precision of our casting operations, with the aim to reduce the presence of mould line to zero.
To clean its mould lines, the most important thing to have is a very sharp blade; the second is to avoid "scraping" the line but to prefer going for clean and straight cuts.
You can use files on surfaces that are more open and accessible, but filing or scraping the surface may create residues that do not fall off like they do with metal and plastic, but remain attached. This is due to the more plastic and flexible nature of the material itself.
If the area to clean is easily accessible, this can be resolved easily; if you are trying to clean a mould line between the legs of a horse instead, this may be a bit more complex.
If I could be of more assistance, please get in touch with me here lorenzo.pala@warlordgames.com and let me see some picture of the parts that are giving more problems, so I can see what can be done and understand if what you received is a model that should be replaced instead.
For wmyers, I am sorry to read that we have not been able to provide useful assistance to you when you inquired about the material. If you like to give us another chance, please get in touch with me directly at lorenzo.pala@warlordgames.com
I hope this helps.
Lorenzo
