Please forgive me pete for imposing on this super dooper thread(given me the chance to see what a normal shell looks like
),feel free to
me.Just thought i'd add just in case anyone wasn't aware, be careful if you happen to use acid to clean high strength fasteners ie high strength wheel studs/bolts and other stressed high strength fasteners due to accelerating(hydrogen embrittlement),unlikely anyone is going to need to derust one in an acid bath but you never know.It's a big subject,anyone interested look it up on the net as i cant upload the paper due to being an attachment upload whore.
