Hey guys!
I've just got myself a nice FC model but I want to get rip of the paint on it...

I normally use 99% Isopropyl alcohol for my normal plastic minis and metal minis and I leave them in the alcohol for 48 hours... I was wondering if this would melt or damage the FineCast plastic in any ways or if it would work fine???
Thanks!

PS: I don't know if this section of the forum is where this post should be. Sorry if it's not supposed to be here^^

I would not suggest isopropyl. Hell, sometimes I felt that even Simple Green was too harsh on Finecast.

It won't "melt" the model in the sense you're thinking of(puddles of goooooooooooooo!) but it can make the material really soft and because the material is very porous it can actually end up 'weeping' whatever you used at random times.

Can you get hold of Dettol? That will strip it but will take longer than Iso.
Don't use Biostrip, before anyone recommends that, it can damage resin if left too long.

Dettol? I'll check it out... How long do you recommend dipping the model in it?

Also, if I can't find Dettol I'll be forced to use Isopropyl since I have to have it repainted by the 22nd... How long do you recommend me dipping the model in alcohol?

It's horrible, but won't hurt resin, there is always dot3 brake fluid if you're in a pinch...

I've had bad luck with Dettol, it turned my finecast CW halberds into soft rubber. But - it has worked for others. So maybe try just leaving it in there for 2 - 3 hours and then brush it off with an old toothbrush. There might still be some paint left but as long as most is gone it should be OK.

Krissp, if the paint isn't too think, you might want to just paint over what's there instead of trying to strip it. Finecast really doesn't hold up well to anything that will clear paint.

Oh bugger, I haven't had that happen, but I'll believe it.
Maybe dilute the Dettol with water as well, just to be sure.

The primer made bubbles because it got cold outside while it was drying...

He was talking about using brake fluid.

I know that hahaha^^

I haven't had any problem with Isopropyl or Dettol, but I don't put it in there forever. Just a little while, then remove with toothbrush. However, I do agree: isopropyl makes the finecast resin very soft, so you need to handle it with care.

I am not a big fan of Finecast anyhow (is anyone?) so it's not like I go out of my way to repaint anything It only happens if I *really* don't like a part turns out and strip/repaint, and in that case, the paint hasn't cured yet. For instance, I might decide I want wings to be black, instead of white. It's really rare. Perhaps that has something to do with it.

I hate finecast and I miss metal models XD
Anyways, it's not really repainting, it's because the primer made bubbles because it got cold while drying...
Since it's only primer somebody told me I could just dip the toothbrush in isopropyl and then brush the model? idk if it'd work...

Ahhh I see. IPA has always removed everything off of finecast for me. How long the primer has been on there may make a difference: I've never tried to strip years-old primer from a finecast model. But newly primed (within days/weeks, even months), no problem. You need to be gentle with the scrubbing though, because it's really easy to break off those fine bits.

It's toxic to Humans.

I tired isopropyl on Finecast, it made it floppy as feth.

Super toxic and really absorbs through the skin. Additionally, you need to dispose of it properly, like not down the sink, not in the bin, not in the ground.
