I'm testing my new flare tool and on the 3/8 stainless, it keeps slipping in the dye. I've produced two flares that look like this so far. I want these flares to be good as I plan on using this for fuel line. If not I might have to switch back to aluminum as it's much softer. Question is, are these flares usable or should I try something different to get the tube to not slip in the dye
