We have been hit with an early monsoon season here in the desert. It looks like it will be dragging for several more weeks. What is an alternate way to prime models(both plastic and metal) without a humidity-sensitive spray basecoat? It can be a brush-on solution, as I'll do just a few models to get my through this humid spell. I would also like to know in case there is an alternate basecoating method that I might use on a few models that I don't really want to spray.
