Hi
I'm `doing up' an old 80.s steel road bike and had the frame sand blasted.
Yesterday I primed the frame with Wattyl Killrust Etch Primer.
Though only non-ferrous metals are listed on the can they guy in the hardware store said it would be fine for use on a steel bike frame.
I have now done a little, maybe too late, research and think that there could be some adhesion issues.
Any advice/insight would be greatly appreciated.
