I'm wanting to tackle a NMF on one of my kits and I've been doing some reading about glues. I've tried the Microscale on some test pieces, and like others I cannot get rid of brush marks. Some guys can pull it off with no problems. I can't. I've experimented with Mona Lisa gold leaf sizing. No help.
I ran across Edgar's posts about how his formula sprays smooth from an airbrush and works very well. He even offered to share is formula with our very own LSP Kevin.
Did anyone ever get this formula?
Just a few things about streaking that maybe you haven't tried:
Use a soft, flat brush that is about 1/2" wide. Just wide enough to fit into the top of the bottle without hitting the sides.
Paint the glue on to pieces of foil that are about 4"X8" so that you can easily go from end to end or side to side without stopping.
Thin the glue with a little water if you feel it's going on too thick or leaving brush marks.
If the glue appears to bead, keep brushing until the beading stops.
Try not to over-brush. If you are still brushing while the paint is getting tacky, you will leave brush marks.
Maybe these are helpful in some way.
