Questions about PMDG 1900D paintkit

[twharrell 38]

I've started dabbling into repaints, and have started with the PMDG 1900D. I opened the 1900d_fuse_t.psd file, which has all the layers, of course.I add paint to a new transparent layer which I place just above the livery layer, but all the rivets are covered up. I can get the seams to appear by increasing the opacity and fill of the alpha seams layer. However, there is no alpha rivets layer.Forst of all, how does an alpha seam layer differ from a regular seam layer?How can I get the rivets to appear under the paint?I'm using GIMP. Thanks!!Todd
