this is how i received the body from T D R. it is so much better than resign it has a uniform thickness from front to back.its close to what 1 to 1 scale is in thickness. the body will need to be givin a super glue paint job to seal it so body work can be done(remember its printed in layers).i use krazy glue in a bottle with a purple top,the top is a brush.i get the from walmart.i would suggest that you do this first and not like i did.i found out the hard way,if you try to do any sanding on it with out doing the glue thing you will find that sand paper doesn't work.that being said body work and triming are just like working with a regular kit.be sure to coat the inside as way.this is so much better than resign,you don't have to grind away any unwanted thickness that usealy gets in the way for scratch building.i'm scratch building everything for this pro mod and the normal stress level that i have when i'm building a frame is not there. i can just build because the inside of the body is so good. i will have more to come.......
