Bill,
Thanks for jumping in here, it was your previous write up regarding Randolph and Sig's compatibility which prompted me to switch over to Randolph and especially for the price benefit. For the moment I'm kind of committed as I just received a sizeable order. I have the color chart from ACS, the one that has twice as many selections as Sig. I've used PPG's single stage polyurethane on a full size plane and I liked it and might consider switching over but for now I guess I'll stay with the butyrate system I have. I have used the metallic silver from Randolph, it doesn't provide the deep metallic flake look I was looking for.
Thanks,
Steve
