Hi
 I've used the shrink tubing guns and they work OK. These
are a little more controlled than a blow torch.
 For a large boards of dual inline IC's, I've use peanut oil.
It has a high enough temperature that it can melt solder,
with a frying pan. I use some long tweezer. To keep them
cool I use a fan ( Don't put them in water. A drop of
water in the oil will be explosive. ). When done, I wash
the parts in dish soap.
 Regardless of which you use, make sure to wear eye protection!!!
