PVA glue is a white glue availible in any hobby or stationary shop. You probably used it in school during art classes to glue paper (or just about anything else!) together. I remember it under the brand name Copydex but there will be many more. My bottle came from a stationers and is simply called PVA glue. (subtle but it was the cheap option). I use it mainly to glue sand etc to my bases.
UHU glue is a branded product and all purpose adhesive. It can be found at
http://www.uhu.com/ and is availible the world over. I think. It also glues very hard and strong. Just how strong I have found on Wikipedia -
The company has achieved one world record in
Germany, in October 2007. A Ford pickup truck weighing about 4 tonnes was suspended from a crane with the help of UHU glue. Two steel parts 7 cm in diameter were glued together with an UHU derivative and were used to connect car and crane hook.[SUP]

This record was subsequently beaten in March 2009 by the German firm
Henkel, who lifted a similar Ford truck, this time with a
Smart microcar in the back, giving a total weight of 5.02 tonnes
Strong stuff then!!
