Aged copper effects

Paint treatment on MakerBot natural PLA at .2mm layers with 20mm/sec outlines printed at 220C

 Metal effects "Copper" paint and "Blue" and "Green" ageing solution from Modern Masters over MM metal effects primer 2x.
I tried a single application of copper and that was a dud..

 Ageing solution sprayed on for second try (one coat of copper did not work)

 Getting ready for the second try, first copper (twice)
