Well it has been a while since I worked with resin, but this Core Works Gp04 kit is such a quality mold that so far its been a walk in the park, assembly wise. Ive got the resin parts washed, trimmed and wet-sanded. I used blu-tack to assemble a rough idea of where everything goes and now its time to start pinning the kit. I can tell the biggest challange will be the propellant tanks on the back. They are quite heavy.
