I am using this stuff to make sure I don't forget what I have torqued or tightened during my build. It is I believe used for tamper protection as well, especially the fly-boys!
This is a revelation to me, as it is so easy to overlook something if you get distracted.
Safety is soooo important, especially if you are responsible!
By blobbing a little of this stuff on any bolt or nut I have properly tightened, I can easily see what I have missed or not, thus providing a measure of extra confidence, especially when I get to put this thing through its paces. It is also possible that it will impress the IVA boys on your diligence.
Coming in lots of different colours, you are spoilt for choice.
I know that some you you builders out there may already be using this stuff, but for those that don't I thoroughly recommend it.
So impressed I was for such a simple idea, it prompted me to have a chat with the supplier and he agreed to let me promote an offer to all you guys who wish to try this stuff, with a discount over any above internet rates (including ebay)!
How good is that!
I am NOT making a bean on this so there is no alternative agenda here...
Here goes:
Provided I can get a minimum order of 10 or more units (tubes) I can get a discount of 15% over and above any internet price on an initial purchase.
So Unit cost will be 3.35 each tube and what is more will be delivered free...
Colours - Please specify what colours you would like for the order:
green, orange, pink, red, black, white, blue, yellow and purple
(they say they have all colours in stock for next day dispatch)
Delivery Time - First Class Recorded - Next Day
Just start a list here of who is interested, and once I get beyond 10 - I will send you a PM on how to obtain your special order.

Torque seal in action:

Remember - I need at the very least 10 tubes committed to - ie 10 people at least (unless you want to order in bulk of course!)
Tell all your friends!
Enjoy!!!
