And to wrap things up, i'm going to post pics of my easy customs (I know, I know...wrong forum..but OH WELL!)
Custom Black Classics Devastator:

I bought two sets so I could make my all green Classics version. I HATED having the center guy green with all the limbs black, so I painted the center guy all black and then added some highlight colors (red, gold, silver). The paint went on nicely (testor's enamel), but I did NOT paint him to transform. There are some hollow green areas still present, but you can't see them. I place him with my Energon Decepticons.

Mr. DeVille?:

This was my first custom TF. I never knew how much goes into painting these dudes. He looks OK, can transform if I want to, but I lost a lot of the molded panel detail with the paint, and some of the paint just chipped off the first time I touched him. I also couldn't get the long middle pin back in so he is technically in two pieces, but you can't tell.
