ah, but which way do you use the gun ? forwards or backwards ?

if done properly, forwards, there's hardly ever a need for any finishing.

Could you elaborate? I'm not sure what you mean.

Andrew

if you are /filling/ a void

cut the nozzle to the correct diameter for the gap

squeeze the trigger on the gun whilst pushing forwards

said tube-gak forces it's self into the void and finishes it's self off

if you are /laying/ a bead of tube-gak instead of filling then pulling the gun
backwards means you're better able to judge the size of the bead

If you're pushing you don't need to "judge the size of the bead", you
just push/squeeze smoothly at the right speed so there's always a
slight ripple of goop ahead of the nozzle but not enough to escape
sideways.
