New to Hasegawa Model in The Workshop! Posted May 24, 2013 Well its kinda being discussed in the thread pinned at the top. Not using hot water isn't really a terrible thing either. Its just a little difficult to get the decal off the page then onto the model and adhere. If you have decal softener or setting solution it really makes a lot of difference to get the decal set onto the surface and adhering nicely. And if its already on the surface and adhering nicely, then you have nothing to worry about!
