You could always try removing the gold from the ponies. I'm sure they didn't come like that. Someone probably took some of that fancy gold spray paint commonly used on lowriders and such (24k Gold would be a brand I'd suspect) and sprayed it with that. Maybe try rubbing it with some mineral spirits (paint thinner) and see if it comes off. Might take a bit of rubbin', but I'm sure it'll come off.
Otherwise ... spray it with fake chrome?
