Hi, nice job so far, i know what you mean by the decals, there are a right pain in the butt lol,
As for help with them, i use Micro Set and Micro Sol on my decals, it works well and shapes them to almost any shape, but when its doing its thing, the decals will make you cry at what they are doing ( they wrinkle up )

i know its a plane in the link, but they are the kits that need the bigest help in getting a decal to form for the painted on look
Hope this is of help to you, and keep up the good work
