I'm using the purple stuff version of simply green (same compounds, different brand), and im trying to strip the paint off of some models for my girlfriend to paint (she paints nids, and I got her some used ones. Her army is mainly white, so I am just going to prime them white for her.)

But by god, some of these just won't strip. I've had them soaking for an EASY 60 hours now, and the black primer spray just will not come off even slightly. Does this stuff lose potency over time? Will it never penetrate the ALMIGHTY KRYLON? Help me before I accidentally melt two carnifexes and a hive tyrant!

Whilst British and having a whole other raft of chemicals to use instead of what you get on the other side of the pond and thus not being aquainted with the effectiveness of simple green. I can say that if black paint/primer has been on a model long enough (or perhaps depending on the brand of paint) it can "stain" the plastic beneath, particularly with black.

However the majority of it would still come off fine, and that doesn't sound like the problem you're having. With them being second hand, are you sure they used acrylic paint on them and not something else? Seen as all the common methods used for paint stripping around here are for acrylic and that might not work on other types. I'm unsure of how you can tell if you can't ask the original owner directly however, nor am i sure on how to strip other types of paint off of plastic without damaging it.

Good Luck

He uses citadel sprays, and krylon sprays. I know the guy personally, so i've seen how he works.

I've stripped the citadel spray with no problem before, so I did some googling specifically for krylon and came up with the following

https://www.reddit.com/r/Warhammer/comments/1bdpok/stripping_stubborn_paint_from_plastic_models/

They suggest that if you want to even think about budging that krylon basecoat you need to up your game, possibly even into brake fluid territory. Be careful with that stuff, it can be hazardous, may start eating at the model, and needs disposed of in the proper manner.

It may be worth thinking about just spraying the white over it at the cost of some of the hard details.

Once again, good luck

What material are the nids?

Have you tried acetone if metal or denatured alcohol?

Trust me, if it were metal it would be simple. ANYTHING gets paint off metal. No, this is new plastic.

Denatured alcohol is ok on plastic, just needs scrubbing with a toothbrush don’t soak for too long though,

I had to strip bunch of models that were undercoated with Krylon last month.

I used Super Clean (the brake cleaner) to soften up the paint, followed by Isopropyl Alcohol. I used the 90% stuff.

The paint reduced to a thick, gunky mess, similar to an ink. It stained the plastic, but an additional bath in the Isopropyl got it lighter. Be careful not to get that stuff on the floors, it will leave a mark.

Good luck!

I had a similar problem when stripping models. Paint came off just fine but the black primer seemed only faded and rubbed off raised edges. I just gave the models a good scrubbing and primed them again. The paint is adhering and I haven't lost any details on the models. I wouldn't worry about it.

Seems GW primer (at least in my experience and the experience of those at my local shop) just does not come off. Only way you can really do it is to scratch off the plastic it's on... which doesn't really work. Then again, I've only used Simply Green (both diluted and non-diluted).

Super Clean > Simple Green. Also, an Ultrasonic Cleaner helps tremendously and you can get them for pretty cheap. But still, there are some paints that simply will not budge. Unless it's a super thick primer, paint over it.
