What type sponge are you guys out there using for paint chipping? I tried to use a small 10/0 brush, but was not happy with the results. The chipping was too big and the effect looked more painted than chipped. I've seen some photos of sponges used for this:
What works best?
I use anything that looks like what you are looking at in the photos. I think I got my sponge from the padding used to keep a computer monitor safe while packaged for shipping.
Are you wiping the excess paint away on a piece of paper or dinner napkin before attempting to place the chips onto your model? You can see where I am doing this in the second photo you placed in your post. See the napkin with the paint on it? Please let us know.
