Hey everyone, quick question for you. I'm working on some Nurgle conversions and I wanted some of the smoother areas of the model to look more pockmarked, dented, etc. Now I know acetone messes up plastic models really bad, but I guess my question is HOW does it mess them up? I know if you leave them dunked in it for awhile they'll turn to goop but what if you only expose certain parts for only a short time with a thin layer of it? Would the affected area "harden" again or is it permanently going to come off? Is it like acid? If i leave it in a dot on the model, will their be a little melted hole in the plastic?

Sorry if the questions seem strange, I'm just trying to expand my repertoire of making messed up Nurgle stuff without having to drill individual damage over and over. Thanks for taking the time to read this.

Acetone turns plastic to liquid and slowly dissolves it...it wouldn't look pock marked It would look melted.

so...like really slow melting ice

Acetone will slowly melt the plastic on the place where it is applied. The problem is how small is the area you intend to apply the effect to. I guess a qtip will be enough to carefully apply then have the area softened then apply some more.
After you remove acetone the area hardens so you can possibly achieve the result you want.
Your best bet is to try the effect on a piece of sprue and then on a model to avoid any disaster.

There's a video on Tabletop Minions about using liquid greenstuff to make surfaces non-smooth. The intro is a bit long (but pretty funny), you can skip the first 3:30".
If it could work for what you want to achieve, it seems much safer.

Turns it into a goopy mess. I wouldn't do it. You'd have more luck with a soldering iron (I wouldn't do that, either).

What about using little drops of bleach? The effect is faster and harder and you still have enough tome to control it, because its not like the typical acid hole. You'll have to wash it with water later, ofc, or it will keep melting. I'd suggest you to try the effect first with the mold, so you can test if its the result you're looking for.
