Stripping FW resin

[Plaguecaster]

Hey everyone due to certain natural events in my area my converted FW Deredeo suffered a rather unfortunate accident breaking a bit as well as being covered in random paints when a shelf holding paints collapsed on the work bench he was sitting on which I started painting but left it for the night to dry ready for the next coat. So I am keen to try salvage him as it was a cool conversions I did, i want to try stripping the paint (mixture of GW and some other ones) but never tried it at all especially with FW (with some plastic parts) any advice would help a lot

Thanks

Simple Green works just fine on FW resin if you have any on hand. I've personally used some diluted Lestoil to decent effect too.

Not sure about NZ but I've never been able to find Simple Green in Australia. Dettol works well if you can get your hands on that (been a few years since I've been over there so not sure what you guys have got). :)

A +1 for normal Dettol liquid if it's available to you.

+2 for dettol.

I usually use methylated spirits (aka the all powerful metho) to strip my models, but I've yet to test it on FW resin. I had stripped some resin bases I got and the only ill effect was softness due to long exposure.

I would have thought isopropyl alcohol would have been a better choice. After all, Dettol contains isopropyl alcohol as one of its key ingredients.

IPA (Isopropyl Alcohol) works for me every time. I usually leave to soak for 3-4 hours and then scrub with a toothbrush (for example) and then rinse in clean water. So far it's removed every layer of paint (Vallejo, MIG, GW, FW, COM-Art) including primers that I've used.

Here in the UK IPA is readily available via Amazon - no idea how that may differ where others are.

 

A word of warning, when soaking resin models, don't leave them overnight as the resin will go slightly soft. It will regain rigidity over time but best avoided if possible, especially if you're wanting to repaint right away.

To be fair, 15 minutes soaking time is all you really need to strip paint with IPA before scrubbing the paint off. Then again, it depends on the strength of the IPA.

another vote for IPA here. Swear by it.

Forgeworld changes resin blends fairly often, so it is worth it to do a quick test before dunking. Most is polyurethane/polyurea blend, and is pretty solvent resistant. However they also use a blend similar to GW finecast on some models, I have no clue what that is or how it holds up to solvents.

I gather IPA stands for isopropyl alcohol ? [Edit: read slower and found the confirmation in previous posts :) we use different acronyms from plastics industry blokes so I'm always confused :) ] I have copious amounts of it in my lab but it's the pure solvent.

 

So, do you use it pure, or watered down, and if the latter, to what ratio ?

 

Because some polymers stand alcohols well, but some swell up pretty massively if the solvent is not an aqueous mix. Even if it shrinks back, swelling is a good way to remove some components of the blend so I prefer to avoid that ;)

Personally I use it neat straight from the bottle, and get it from Amazon (linked so you can see the contents label).

Corswain you can get simple green from most bunnings in one form or another (concentrate or straight)

Next time I'll try stripping on the rocks
