Aircraft and automotive crossover question.

[Whitney Paine]

Hi,

My field is classic cars, but you gentleman - and ladies - deal with making mechanisms in a high vibration and difficult environments work reliably.

So if you could help, I have two questions:
1) A lot of my fasteners are "wired" for security, but for those that are not, could you recommend any kind of "Loctite" type product that can secure the fastener reliably? Hopefully, Loctite is not a dirty word!
The reason for the question is that sometimes originality issues mean a part is not wired, but nonetheless vibration on some cars can be awful, causing items to work free.
2) What types of stainless steel do you use?

Thanks for your time.
