I use an autoprimer for the undercoat available from my autoparts supplier two blocks away.
I use Tamiya acrylics, mostly. They're cheaper than the GW paints, give me better coverage, and are more readily available (I don't have to go to a GW, but several model shops in my area stock them). GW still don't do the right shade of olive green that I want on my IG.
I do use a few GW paints (some of the washes and some of the foundation paints.), though.
Glues: Anything but GW for superglue. Revell Contacta Pro for plastics (less than $4 for a 25g bottle, puts the glue where I want it, and lasts forever.)
Hey! Where'd ... Everybody ... go?
