Nothing to do with UHU 02 models. I refer to the adhesive, Uhu. Although I normally use a white glue (elmers or similar) for most asembly, I have used Uhu to add reinforcement. In particular, its good to use as a type of filler. Basically, pour in some Uhu into a modular section of a build and add any small card off cuts to the mix. This forms a tough matrix when it sets, making for a solid structure that is less susceptable to accidentaly being collapsed by the ham fisted (like me). I used to be able to get bulk containers from my local hobby supply store and from a stationary supply shop. They have both stopped stocking it and only sell smaller tubes. Indeed they are switching to the useless non-solvent based version of Uhu as well. Anyone know of a UK stockist for the solvent based bulk pack?
