Looks pretty sharp!
I was surprised to see you undercoat the body. I have never done it but there's a lot of controversy on whether it's good or bad - traps moisture, makes rust worse, miserable to deal with later on, etc etc etc.
Have you had good luck with it in the past? I had thought about doing it on my M38 but discarded the idea after hearing so much negativity. Then a world renowned author shows up and throws everything I thought I knew into a state of flux.
What's your take on the stuff?
