As my second attempt at trying something new, I experimented with using UV light and fluorescent paint to create a glowing effect.
The kit is an HGUC Gundam (not the Revive version), and the only modification was extending the thighs by 3mm. It was painted in a so-called "real type" color using lacquer paints.
Enamel washes and dry brushing were then applied.
Using the Bittrade-One UV light that LA 8-24 recommended, I painted it with Vallejo fluorescent paints.
The thumbnail image shows the result using the UV light.
