Now, for this Gouf, I've decided on an easy finish using the molded color, but I'll at least deal with the seam lines.

I've uploaded a photo of the finished product as the thumbnail, but I think it's probably hard to tell from just that.

So let's take another look at the seam line treatment process (CV: Masamune Kazunari)

Erasing the seam lines significantly improves the quality, so I highly recommend this step even for builders who prefer not to paint.

Using finer grit sandpaper will make it even smoother, but personally, for a typical HG size, I think finishing with around 600-800 grit is fine.
