I did a corrosion dye test on some backstay hardware. First, you clean the hardware with "cleaner/remover" (seems like acetone). Second, you spray the dye on (see picture), and leave it on for "one to thirty minutes" (what happens if I leave it on for 31 minutes?
). Third, you clean off the dye with the cleaner/remover, then apply "developer" which brings back the dye in any corroded areas. The test indicated corrosion in two places where it was apparent without the test. However, it also illuminated about an eighth of the surface of the the hardware in the picture. This was not a crack or line, but an entire section which appeared as perfectly sound stainless without the test. I wish I took a picture, but I didn't. Picture the top left section of the hardware (next to the hole) red, and the rest of the piece, shiny stainless steel. Anyone have any idea what this might indicate?
My guess is porosity, perhaps factory original. Those dyes are penetrants and to colour an area, rather than a line there would have to be some kind of porosity to the metal - this is not a form of cumulative failure mode AFAIK
Those T-bolt turnbuckles are nasty things IMHO - replace them with proper jaw to eye ends.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
