We can significantly enrich gunplas and also industrial machinery by adding additional panel lines with a burin, or a specialized scribing tool.
Creating complex shapes without damaging the model is difficult, though.
To make it a piece of cake, you can use any of these scribing stencils. Just pick the one you want to use, hold it in place using masking tape or similar, and carefully engrave your panel lines.
We have to prepare each shipment individually as they are ordered, so allow it in 3-4 weeks to arrive in the USA/Canada (to be safe) and 3-6 weeks rest of the world, though they are usually delivered much faster.
