Seriously, or are you kidding?
I'm not kidding. Do your own investigation of course, I did before I tried any kind of manipulation. Separate the fur lightly with your hands on different parts of the figure and look at it below the ends/surface and you'll see the original acrylic is two-toned throughout in brown only. Pay close attention to how the fur feels as well and you'll notice it's matted and stiff precisely where paint has been applied.
I think some people still don't understand, so I'll repeat it again. Alcohol only removes paint that's been applied to the acrylic faux fur. It doesn't (and can't) affect the color of the acrylic itself, which is two toned - there's a darker and lighter brown in the actual acrylic fur strands. You can't change that brown color of the fur itself, so if you find some areas are too dark or too light because of the fur's own color, the only thing you can do is add pigment to cover it - paint or chalk for example.
We've seen figures that have more and some that have less black paint spray. It's this spray that's been responsible for the variation in-hand others have mentioned and some complained about. Speaking specifically about the head, yours may or may not have excessive or noticeable paint, so there may or may not be a significant amount of material that can be removed. If you want to make any portion brighter than the actual fur color itself, you'll still need to ADD pigment.
You don't want to share pics of it? Fine, your choice. But to berate people for asking about it...wow.
I'm doing no such thing - what is happening is I'm getting tired and a little annoyed at people making assumptions and demonstrating an un-called for air of entitlement and essentially "demanding" photos. My figure isn't assembled, I have more work to do on it and taking high quality photos, the only ones that matter, takes time - time I don't have much of and that I don't wish to spend on this particular subject given everything else I have on my plate. I typically have always posted an abundance of photos, including how-to images of all manner,
but I don't have the time for that now.
So if you're referring to my comment about compensation specifically when you chose to use the word "berate," you're still off the mark. I'm getting paid for every photo I take at the moment and every minute I spend setting up and processing the images - the return is very good I might add. So if I'm going to take time away from something else that's helping to put food on the table, I need to be compensated to make up for the loss. Take it or leave it I suppose, but my priority is my customers.
