マッドワークス モデリング用接着剤 - ブラック（高粘度）

Needed something that could handle both gap filling and bonding, and this black glue fits the bill perfectly. The 3-5 minute cure time gives me just enough working time before it sets hard enough to sand down smooth.

Picked up a bottle for filling seam lines on my Gundam, and it’s exactly what I needed. Dries in about 4 minutes and sands down smooth without any cloudiness.
