I work for a company that manufactures rocket engines (including the space shuttle main engines). Years ago we used a lot of WD40. We had a rash of problems with bad welds on welded assemblys which were eventualy traced to WD40 haveing impregnating the metal and causing cracking and porosity. It was found that WD40 could not be intirely removed no matter how powerfull a cleaning process was used. Since that time WD40 has been banned from the factory.
Our labs say that it contains silicones which are a no-no around welding. WD40 says no silicone in formula. Oh well, whats a mother to do. We use Amsoil spray and Kroil spray.
