And there's more. It seems paints are becoming more wanted lately.

Sounds about right, good paints like these one are often overpaid for because people want them NOW, and there's no easy supply of em.

And as above showed, they sell fairly often for more then they are priced at currently.

Even on trade server's I've often been offered two keys + rec or two, which depending how you price keys is easily 6.
