Just something I wanted to bring up about fuel proof paint. The term used to be hot fuel proof and that meant the exhaust and oil. It never really was meant to be able to withstand direct nitro fuel for any length of time. I have seen model paint now stating it will be able to withstand fuel with up to 15% nitro in it. It just never says for how long. I just had some Klass Kote flake and peel after a fuel tank leak. I also used no primer, I just painted over the glass but I glassed with straight lacquer. That was the first time I have ever seen Klass Kote soften and peel off??
