Different chemicals can interact with different metals (as well as other metals, putting stainless into aluminum as an example). I just used the brakeclean as an example. I am not real familiar with the wave lock bolts. I personally don-not like them in stock rod applications. But I know that using chlorinated brakeclean on titanium is a big problem. There is a chemical reaction that hurts the structural properties of the titanium. So maybe another chemical that reacts to the wave lock bolts came in contact with them..
This was just a “thinking about it” deal. I am not saying that is what happened…
