Notice also that I had trouble getting the primer to go on uniformly. It was scratch resistant on the sheet material, but seemed to easily de-bond from the 1/8" plate. I think the latter was because I didn't slap it on thick enough. Surface prep was to scuff with brown Scotch-Brite, wash with warm water and Dawn dish soap, dry, then apply the coating.
You might think these random pieces of stuff I make are useless. Not so! I'll have you know that this latest creation of mine was used as a scoop to rescue a crawfish from the neighborhood street. My wife tells me that the handle on the side was helpful.

I have heard that Tempo zinc chromate is terrible from an adhesion standpoint. And it's very toxic too.
I have used some Sherwin-Williams 988 automotive primer (rattle can) with pretty good success. You can buy it at their auto coatings stores. There's one in SJ near the airport.
