Hey Derel, if you're interested, PM me for info on my painting services. I can do excellent custom paint schemes. Just PM me what you're wanting, and I gurantee I can give you a great price.
Depends on what style helmet your doing. I did ROTJ and used spray paints that Lynn posted on here. Search for helmet paint and you will find the list.
A while back RS spent a good deal of time comprising a list of colors and technique for painting an ESB helmet. I have found it to be very comprehensive and am using it for painting my ESB helmet. Many have used the same technique and have had fantastic results.
