Whats it called?
You know the paint that manunfacturers mark on some bolts/nuts to either (a) check the nuts arent coming loose (b) tamper proof the part.
Ive also seen them used by breakers to mark parts with their initials etc so they can be sure returned parts are the same.
Alternatively, does anyone know of any threadlock thats nice and bright that could be used to both threadlock and denote a visual check the bolt/nut
isnt coming loose. Most seem to be a fairly see thru'.

How about THIS pretty sure this is what the breakers use, don't
think it has much locking strength.

Nail varnish is quite a decent hard wearing marker... just ask your missus to buy some for you, or raid her make up box... 
(By the way, there's a difference between 'tamper proof' and 'tamper evident', no amount of paint will make a fixing
tamper proof...  )

Either tippex or a touch-up paint/pen.
Lok-tight has to be on the thread before assembly so won't work applied after/externally. Only sets in an air free enviroment (anerobic) as in
between the treads.

Yeah I realise that, but was thinking it would be easier to do it as one job - ie threadlock on thread, tighten, mark, move on.
If there is nothing that does both which seems likely there isnt, I will use two products. I just want something to reasure me and IVA man.

Only problem with paint instead of tipex is if you ever remove and refit a nut/bolt, you have the old marks as well as new ones. Tipex tend to break
off when removing.

In my opinion there is very little need for thread lock products in general service, if something is tightnened correctly it doesn't come slack
again. Usually fasteners come slack because they were never tight enough or the application causes the bolt to loosen such as a bracket which flexes.
Generally thread lock is only required where the fastener cannot reach the required tension to be self supporting, cases such as into weak materials
such as plastic or into material where expansion rates are very different.

there is a specific name for the stuff your after, we use it at work after torqueing up stuff on aircraft during heavy maintenance. It's a
bright orange liquid that sets hard and breaks off when you undo the nut/bolt, it comes in like a tipex pen, sadly after all this waffling I
can't remember what the hell it's called!

all true, but for some safety critical bits I know I'd still use a dab of threadlock even if all it does is help me sleep better...
mind you there are many more parts were I use copper or graphite grease to make sure I'll be able to get them off again lol

It's not designed to be, it's just a visual indicator of something coming loose.

I've not long ago brought a KTM 690 single cylinder beasty ,,if everything wasn't loctited up it would of fallen to bits by now . And i
would definitely check on the plastic before adding loctite as some plastics don't like it .

Just to make a point if you're pre IVA i found stuff like this gives you lots of brownie points with the examiner. Shows your safety conscious.
I wirelocked everything I could ie prop bolts, reverse box bolts, caliper bolts and the examiner was well impressed and IMO was a little more lenient
on other things that could have gone either way.
