Hi all,

In my experience of de-potting NSTs, I wouldn't take the tar out of them
Heat them up very slowly in an oven, and allow the tar to melt. Then,
maintain the temperature for about four hours. This will allow all the
cracks andd bubbles in the tar to dissappear, and all the air to rise to the
surface. Unless you are actually depotting to deshunt, then I would
reccomend that you dont actually remove the tar, just melt it. Removing it
is messy, and disposing of it is even messier!!!

Regards,
Jason
