So I've been using Sculpy as my primary sculpting material. You're using Fixit? How long does that take to cure?
I wonder if I could bake sculpy onto my figure parts without melting them.
I personally use Apoxie Sculpt, although I wish I had bought fix-it as I heard it's better...I just didn't know at the time, and thought apoxie sculpt and fix it were the same.
As for sculpy, that's I first used when I got into customizing. In my experience, depending on the figure, you could bake the sculpy on without melting the figure, but that was on Marvel Legend figures, softer plastic like on star wars figures might melt. Also, I found that after baking, the figures were never the same, loose, wouldn't stand straight, etc. Also, you'd ideally want to sculpt little by little, which means you'd be baking several times. On top of all that, I find that sculpty once baked, looks like clay on the figure, which is exactly what it is, a type of clay. With the Aves product, you can build on your figure little by little, and the end result is a strong rock hard piece, that if smoothed properly, is so smooth, you could confuse it for plastic.
I find the total cure time to be sometime after 5 hours or so, but even before then, it's pretty hard and tough to work with.
Within the first 2 hours is when you want to really get in details...at least that's my experience, although honestly, I've never timed it, so I could be off.
