When making Gunpla models, what is the specific operation of the penetration method? How to do it?

1. Preparation tools: Zippo oil, black paint, thinner, facial pen, palette, Gundam marker, cotton swabs, straws, and one Gundam model part.

2. Use a marker pen to mark half of it as a reference.

3. Then mix the paint with enamel paint and solvent. Their ratio is one to three.

4. Dip the paint pen into the groove, and the paint will automatically flow along the groove line. If the groove is relatively shallow, you can use a scribing pen or pen knife to deepen it before bleeding.

5. After the paint is slightly dry, dip a cotton swab in Zippo oil and wipe the spilled part.

6. After wiping, absorb the excess Zippo oil with a paper towel. Be careful to absorb it and not wipe it.

7. The seepage line is now completed. Through comparison, you can see that the seepage line is thin and beautiful.
