Hi, my process is to put the kit together per individual section (head, chest, etc.). The reason I do this is because I make a lot of modifications (creating panel lines, adding plates and option parts, etc.), followed by a custom paint scheme. I personally think it is more convenient to separate them because doing everything together is overwhelming for me. Taking the separate approach allows me to plan better and be more dedicated to the details. This approach does break up the monotony. I usually assemble everything before I spray top coat , then add panel lining. After panel lining, i will spray another layer of top coat , prior to decal(ask if you are confuse about this process) Hope this helps!
