Hi!! Just finished up another rod and I have a question. The blank is black in color and I used Gudebrod Nylon #245 Royal Blue with gold accents. The blue looks great. I had this problem before and just lived with it but I dont want to this time. I have some Flex Coat color preserver and thread sealer but I dont know if I should use it. I dont want to darken the blue on the rod. I tried it on a piece of the thread and it darkened it. Am I doing something wrong?? Or should I just go and forget the preserver and coat the rod with the high build??? Please help, I'd like to keep the nice color. Thanks in advance.
