Thanks! So far they have just received a few watered down acrylic washes. I paint it in all the recesses, let it sit for a few minutes and then try to wipe it all away. Then a similar approach for the main body. A full wash but then immediately wipe it all away. I only do a little at a time and let it build up. Each time I get his new saber, they others get another wash if I feel it needs it. The Mace Windu has received the most washes and a heavier coat in the grip and around the buttons to try to match what I saw in the promo pics.
As for the bar LEDs, I went onto eBay and purchased some real LED bars, you need to sand them to be shorter to fit in the recess, but I think it helps make them look more like the originals to use the real part.
