Just a general question for those who own any Citadel Finecast models.

I know about the general rule of washing resin parts before assembling or priming.

Reason I ask this is I bought up a bunch of new GW stuff back in 2012 which was all 8th Edition plastics and metals, and also some Finecast produced in 2011. I did not begin to unpack it and start to finally build and paint it until just recently, 2017.

Would there still be mold release agent on Finecast parts even after five to seven years in the package? I also have some Fenryll resin stuff still in the original sealed blisters that is even older, probably mid-2000s.

Does resin stuff that has been packaged for that long still require washing? I guess better safe than sorry.

One thing I do remember though, is that I also bought several resin buildings from Stronghold Terrain back in 2012, and didn't get around to building those until 2015. On one of the townhouses I completely forgot to wash the parts ahead of time. But they assembled and primed perfectly, didn't seem to be any different whether I washed them or not. Stronghold Terrain's buildings are a combination of that more plastic-type resin and that hydro-stone/plaster type parts. What I remember is that the roof parts were the more plasticy type, and the wall pieces and chimneys and things were the plastery type.

I was also wondering what your experience is with buying vintage metal minis still in their blisters. I've got some GW metals from about 1997 that have spent twenty years in their blisters. I can't imagine that mold release agent could last that long on a mini.

I've never washed plastic or metal figures.

I wash resin figures but I imagine it is actually more of a superstitious thing than practical. Still, why not? Water and soap are pretty cheap and if you put it on a paper towel, especially this time of year, it dries fast.

Hey Pictors,

Thanks for the reply. Yeah, I'm talked to a lot of gamers who never wash anything and they never have had any problems.

Some gamers have said that with certain resins, primer will not stick to it and it beads up on the model. I've never had that happen. Many times the "release agent" is apparently nothing more than a soap-type compound and doesn't really affect priming or painting. Other times it might be a chemical of some kind that could potentially cause priming issues. Depends on the company making the minis.

But that kind of leads to another question for me? Is Citadel Finecast more of a resin or is it a plastic? It's kind of weird stuff. It has the look and feel of plastic, especially when you're trimming and cleaning it up.

But I agree, if one is worried about it you might as well wash them for peace of mind!

I don't know about Finecast, but with resin generally the effect of the mold release agent can be more insidious than just causing paint to head up.

Instead, the paint will sometimes appear to adhere just fine. But then days or weeks later, it will start flaking off…

I never washed finecast before priming. I never wash resin in general for that matter (I also build 1/35 military models, so use lots of resin in that capacity), & I never had an issue…

Ok, I bought some resin buildings on sale and have never done anything with resin before. Do they need to be primed and with what? Does it matter what paint I use (usually craft paint)?

@Col,

Resin building pieces should be washed with dish detergent and warm water. In some cases it's probably ok some of the time to not wash resin. Trouble is you don't know what kind of mold release agent the company used, so it's better to wash it either way.

Any kind of spray primer can be used, hobby or general kinds like auto primer, etc. I use Armory hobby brand black spray and it works great for resin.

I also use craft paints, they are ideal for primed resin. I have a combination of Michaels Crafts paints and the brands that Walmart carries.

This is what I was able to achieve with craft paints:

In this age of 3d printers, bones, crowd funding, its hard to tell just what you are working with. I suggest washing everything.

I really haven't had many problems with the unwashed but I get the occassional chip or rubbing off which may be weak primer or not washing. Hard to tell.
