Slow progress but I'm trying to work on at least something each week. Did some more sanding on parts, Taped up a few parts and sprayed black primer on the underside of the pieces. Thanks to Andrew for reminding me that I should tape up the areas where I'm going to glue. I might spray another coat tonight and then I'm going to let the paint cure for a few days before I put a clear coat on it. Probably going with matte since it's the underside, and really just doesn't need to be bright white.
Side note, I'm planning on using magnets to secure the chest, and was thinking about using magnets for the shins as well. I'm trying to decide if it would be worth the effort vs velcro. Velcro is super easy to use, and the industrial strength holds pretty well. Magnets looks like a lot of work and planning, but would be nice to lock in place when kitting up. I might use magnets to secure the spats. Still haven't decided.
