Scratches
 

About the scratches, if the scratches are not too deep they will be cover and buffed out during painting. The exterior part of the plane will be slightly sanded before painting then the primer will help fill in small scratches.

This, and you will put your own scratches on things as you build. It's gonna happen even if you try to leave the protective film on. Congrats on the kit, it's a fun learning experience!
