I ran into major problems when I did the panel lines.
First I used a weathering set Tamiya Weathering Master B Set, using water and a thin brush to apply the chalky thing. i let the thing dry and it just won't come off with water. So i used some thinner and omg it came right off with paint job too.
Second I tried to use some acrylic paint thin down with some water, it applied ok. When it was time to remove the excess... again it too off all the paint on the model.
what products should I be using to remove the excess paint or weathering, without taking the whole paint job off.
I did coat my whole paint job in some clear gloss coat to protect the paint, but it still just took off.
