Gunze flat base Does anyone have information on just what this stuff is supposed to be used for? The owner of the shop I go to says that it is to be painted on bare plastic to make paint adhere better. Tried and got white chalky crap that rubbed off on my finger and couldn't paint over. My thouht is that it is for mixing in the gloss colours to reduce tham to flat but them if that is so why do they make a separate flat coat. If anyone can help I would appreciate it.
Thanx; ron
