One of my favorite steps Priming! Mr. surfacer 1000 was used with Iwata 0.05 needle nozzle combo for glass smooth coats.
I Also cut the bottom of the torso with hyper saw and added 1.5mm Pla plate to the bottom of the torso to give some length to the waist and stomach area. I felt it looked squashed and busy left alone.
I proceeded to mark center point and drill a hole for the peg which was replaced with Brass rod given extra length and ability to separate the torso from waist easily without harming surrounding paint.
A few Pics are showing first coat of primer sanded back since first layer is to help show uneven surface and flaws.
Head showing how scraping at corners of meeting parts can add a ton of depth to a part.
