This test scratches an itch I've had for a while now. Not that long ago towards the end of my Military Bulldozer build I was attempting some weathering down along the running gear and the bottom of the chassis. For whatever reason the chipping fluid I was using was not letting go of the top coat of paint and everything I tried was just going straight through all the way to the plastic. which was yellow. Understandably you don't want yellow showing on your standard issue Green Bulldozer.
Don't know if I completely resolved the issue but I've definitely got another club in the bag if you will.
