Having read on here that Lechler epoxy primer doesn't contain isocyanates, I was a little alarmed to find when I had some delivered that the label says it does. I emailed paints4u and they admit they've put the label on themselves as a general safety warning. It doesn't however actually contain isocyanates. Make of that as you will.
My question here is what preparation is needed before spraying. I aim to sand and grind the metal as rust free as possible, but I know that at the microscopic level it will be still be full of gigantic gouges of oxide. Is it better to try and treat this with a phosphating product such as Metal Ready, then epoxy this, or just spray the cleaned up metal?
