I have just a very minor update, more of a gameplan. I'd like to show folks how easy it is to do this. Easy but time consuming.. I started working on the flooring. I made the floor grate, it's not screen accurate, but it's more of the Kenner style. I just cut .03 styrene to shape drilled holes and used a small file to shape the holes.
Also I put the first coat of lightweight spackle on the floor. The reason I do this is; 1) it fills gaps, seams and smooths out inconsistencies. 2) it creates a stone, concrete or stucco texture. 3) I like to use Woodland Scenics earth color watercolors and they work perfectly with plaster or plaster like products.
I will probably apply 3-4 coats, sanding between coats. I've done this several times before, and I find the more coats the better. As you can see on the Star Wars WW2 bunker I made on the very 1st post on pg.1. It's just time consuming, but I have plenty of time. I have to do the same with the wall sections, then fill the seams after the wall sections are assembled. So it's a process.
