I understand the religious debates, but there doesnt seem to be many “just clean it and dump it in alclad for a few minutes” believers out there. A few suggestions about it’s use: This all depends upon your alumnipre; of “durable barrier” between substrate and environment.

Only time will tell who is right. These suggestions are purely based on my own years of trial and lots of error.

You’re eating up metal at that point. I ask them about preping and primeing when the metal alumnipdep an alkalad surface.

How are you guys disposing of your spent alumaprep and alodine? Just follow the instructions for application. Keep the part wet between alumiprep and alodine.
