I was painting and plating some parts today, which I'll share photos of once I finish up this batch. But with the snow melted, I re-discovered some early test pieces that I'd plated just over 4 months ago. These were freshman attempts, before I'd dialed in my system and process. But I still thought it was worthwhile to do my own corrosion test. I set these samples down directly on the dirt just over 4 months ago. Shortly after, they were covered with about 2 feet of snow. I just examined them this morning. They look pretty good. No evidence of corrosion on the top surfaces at all. The yellow chromate converted pieces look great on the bottom, too. The silver ones may be showing signs of early corrosion - or staining - on the bottom. These are blue chromate converted which have a higher salt spray rating. I don't know how that translates to laying in the dirt. I also don't know how "direct dirt contact" translates to actual automotive use. Presumably, the parts on the car would never be laying in the dirt for 4-months (at least I hope not). I'll continue to keep these out there as long as my wife will tolerate it.
