I gleefully purchased this kit at Yamashiro-Ya in Ueno, Tokyo in the early 1990s. Resin garage kits were all the rage at the time, and this kit was fully representative of the best you could find in those heady days. It had it all - outrageous subject, outrageous detail... and outrageous price (12,000 Yen)! In addition to the resin parts, a PE fret with various fins, vanes, and vents was provided, along with some coiled hoses and brass wire. The instruction sheet included a really cool comic strip which originally ran in B-Club magazine. Kotobukiya was selling their own brand of resin de-greasing detergent called "Liqcaper", and a small bottle of said detergent was included with the kit. What a package!
After returning home, I marvelled at the pile of resin parts that just oozed with insane detail. And then I realized I had zero experience with resin kits. The parts were extremely well molded, and cleanup was tedious only because of the intricate details. The PE parts had no means of attachment to the model, so it was all DIY. The resin parts also had no locator pins or aids either, but to be fair the kit was "free pose" in design to allow the builder to adjust to taste.
So after cleaning up the kit and giving the parts a wash using the included Liqcaper (which worked very well in stripping all the release agent), I assembled a few parts, added some locator pins, and applied some primer. The arm supporting the enormous gun was the only kind of wonky looking bit in the box, and I had no confidence that the spindly thing would support the gun's weight for any appreciable time. What to do? What to do. And then it sat in the box until I could figure out how to put this beast together.
Funny how 30 years changes one's perspective. My younger self did all the heavy lifting by cleaning up most of the parts (the big, block-like energy capacitors for the main gun are still untouched), repairing a few broken parts, and adding some small details. The articulated gun support arm will be replaced with a suitably bent up piece of wire with my own details. I was really taken by the box art, but had no idea how to get that aged effect. But model painting has evolved greatly in recent years, so achieving that look (might) be in reach.
