I am about to start painting and weathering my first MS_1 helmet. I have applied both the primer and silver paint (both Testors). I prefer to use Testors Model Master paints but I am trying figure out if I should go with acrylic or enamel. Acrylic is much easier to use especially with a cheap airbrush but enamel paint is much more durable. I primarily use MM Acryls on my plastic and resin model tanks but are they ideal for a fiberglass helmet that I may decide to wear out in the elements? Would a few coats of dul-coat over the acrylic help? Am I worrying about nothing?
