I bought a pack of woodland scenics tree armatures and some of the covering, I think I got clump folliage and Hob-e-tac. I did as the plans said, brused on the hobetac and then the greenage, all I did not do was spray it w/ scenic cement. after a day all the greenery started to fall of of the tree so I sprayed it w/ scenic cement, but that made the grren clumps that were stuck on very good at the beginning fall off:curse:. What am I doing wrong, or not doing. I watched the video at woodland scenics website, and no difference between how I did it.
