First off to me windows are very important.But also what is the subject matter and do you plan to re-build the whole kit or use it for parts.One other thing is-is there a personal attachment to this particular kind of car or model..I've currently started on a 57 chevy that my brother built about 53 years ago and was found after many years -he built it a few years before he went in vietnam and never came home.This one has a personal memory to it.There are many many reasons for glue-bombs,I'm also doing some restos for another builder on this site-they mean a lot to him.Being i retired about 3 mos. ago i have and love all the time i have to work on models.
