I have had my AR built for some months now. It looked noce without any "custom painting" or color fill. I was over at one of friends houses and, he had the same lower as I did except, he had color fill on his lower. I think at that moment, I was bitten by the "color fill bug". I went to Michaels craft store and bought some materials. It started out looking ****ed up but by the time I cleaned it up, it looking like it was done professionally. Here are some pics of my work. Have any of you done does this to your lower? I would like to know that I am not the only one to do this.
