Well they are holding up nicely in the box
haven't used a single one of them yet really, I did put some of the rear sub frame back together, but that's never made it out of the attic yet.
I did a test with two bolts on the old celica, one went rusty in a week, the other was perfect until I removed it. When I mentioned this to the zinc players they apologised and have since put all the stuff I give them through the zinc plating process twice, the method they use is like a big drum and it doesn't guarantee total coverage with the zinc...hence putting it through twice to increase the odds.
With all the effort I have put into this rebuild, I hope they last a lot longer than a week.
