I am my own worst enemy.. for a whole 2 hours in the lead up to pouring i just kept saying to myself... i should probably just stick a line of hot glue or sealant between the 2.

Then when it started dripping i just kept saying to myself... see i told you it would of taken all of 2 minutes and now look at you.

Its leveled amazing at 10mm you can look down it and it looks straight as anything.. my only worry now is that it goes off hard enough? I've currently got 10mm of very stiff jelly for some rails. Surely it will be fine lol.
