it says on the packet leave to dry 4-6 hours if +10oc, drying time can be shortened if a little heat is used.

well i've stood said item infront of my fire, how long should i leave it?
the temp there is 45oc, would a hour do?

 

all the people online atm and not one of you a bodger!?

 

Yeah I've used it and it's shite, use chemical metal instead if you must.

 

"can be tapped, machined, cut.." id like to see u try!
