Gold/Brass Spray Paint

Gold/Brass spray paint, like Krylon or Rustoleum, is relatively painless.  Some brands look better than others, but overall you can get a nice reflective finish that is very slick.  Unfortunately, as this is a spray paint, you will have to go through extensive masking for any application to prevent overspray, which takes forever and never works anyway.  It also goes on somewhat thick.  

Some brands react strangely with certain toy plastics or modeling compounds (i.e. Super Sculpey), because they are mostly enamel-based, and can remain tacky and smudge.  It is also difficult to paint any detailing over chrome spray paint, because its slick surface doesn't allow other paints to stick.  To get around this, you have to mix the detailing paint with gesso or some other type of medium.

Gold spray paints, like the Krylon featured in this picture, tend to have a very dark, yellow gold appearance.  If you're looking for a lighter, brighter shade of gold, you might try a brass spray paint instead.

Pros                                Cons
· Cheap                         · Masking is a pain
· Easy (broad coverage)           · Detailing is difficult
· Looks pretty good       · Even though it looks good, you can still tell it's paint

Synopsis:
Use mainly for broad coverage or an entire figure, or you'll drive yourself mad trying to mask off sections.  Overall, looks pretty good if you recognize its limitations.
