I didn't think it was possible, but I just did it and it isn't hard at all. See, about a month ago, I smashed my finger and lost the nail. And it grew out with a huge lump in the middle of the nail. So I needed the acrylic to smooth out the nail so it doesn't look completely gross.
Nailene makes a kit for $7 at CVS that includes the acrylic powder, liquid, a brush and a buffer. Bought it last night.
I watched a tutorial on YouTube and it was really, really easy. I'm quite proud of myself.
Here's the first video on how to do it, if anyone is interested:
