Terry,

The ONLY way to completely remove the coating without damaging the parts is to soak the parts in Sodium Hydroxide heated to approximatley 150 degrees. This is something you do not want to try at home. After the coating is broken down by soaking, it has to be rinsed in clean water and dried. Then, the blast process can be done. An aggesive media has to be used to give the part some "tooth" for proper adhesion. Glass bead and soda blast is not ebough.

It's not really a trade secret, but there is not that many people (companies) that can do this process.

When I receive previously coated headers, this step is always performed before I recoat.

It can be blasted off, but it will take a long time to COMPLETELY remove the coating.
