Got ferrus manus this weekend. Everything looks great, but his two backpack servos are, even after washing, glossy and have a somewhat sticky texture. I had this happen previously with my Abbadon model, but was at Adepticon so I was able to exchange it on the spot. My questions are twofold:

1. Does anyone know why this happens? This is more for my curiosity than anything.

2. Will the resin take and hold primer and paint? I'm concerned it won't. If it will, I won't worry about calling FW. If it won't, looks like I have to call em tomorrow. Thanks!

I've never encountered stickyness before on my Forgeworld stuff. I know some pieces will still feel very slick/slippery even after washing.
The only gloss I've noticed is on those big chunks of resin (the "gate" I think its called, where the resin flows into the mold). If you have the same things, you can always test some paint on that chunk to find out.
Sorry I couldn't provide any definitive help.

From what I remember, this is due to the resin not curing properly. I'd ask for a replacement.

That's what I thought. Tanks!

Would some superglue not fix it?

As stated before this is because the resin did not fully cure. Usually happens when the mixture is off or not mixed well enough. Sometimes it will cure given enough time (Months). It will usually accept paint but will seep thru the paint as it continues to cure. You need to get them to replace it.

Glossy parts are usually a result of too much mold release being used. Resin will duplicate the texture of the parts and if they are slick from using too much release the parts will likewise come out overly smooth.

Sticky parts are from the resin not curing properly. This is usually a result of the mixture being slightly off as proper mix ratio is pretty sensitive. Another common problem that occurs when the mix is off is that the surface will cure but the insides will be slightly liquid or can be soft and crumble depending on which way the mix is off. If the mix was off the resin oils will continue to leech to the surface over time which causes problems with the models durability and also causes issues with paint.

Casting being done in too cold of a temperature as cold inhibits the resin from curing properly which can cause a sticky texture or soft bendy resin, but usually it finishes curing over a couple days time and shouldn't be occurring by the time it arrives with a customer. (which indicates to me the mix was probably off)


You can eliminate some of the sticky feeling on the surface by soaking it for a few hours in simple green. But sometimes even that won't work very well. After a cleaning soak the best thing to do for troublesome resin is to use a commercial primer like krylon spray paint or rustoleum as it will hold to the surface better than acrylic based paints.

This is all very good info and advice !


That said, if i paid forgeworld prices and possibly shipping rates, if i got some improperly cured resin from them, i'd be calling for a replacement rather than taking any of those steps.

Their stuff is ridiculously expensive enough as it is to warrant a product in it's proper condition.
