Scott, I do not see all that many replies here. I am sorry to say I know next to nothing to armour, but just wanted to give you a heads-up to go to the relevant sections and check out what people are doing in their build-posts. I've got a lot of great tips on aircraft from the WIP group on that subject, and I'm certain that it will be rewarding to go check out what tips and tricks others bring in their posts.
Hope this has been of some help, and sorry that I was not able to give you some really useable tips. Happy modeling!
