Be extra careful with true CARC, it is the agent that is the nasty stuff , so be careful when sanding or welding, there is a CARC replacement made by Gillespie coatings that you can purchase in the US, this is the colour only, no agent, also there are other colours for older vintage ammo cans ie WW 2 from TM9 Ordnance Products, hope this helps,
