So far I've used Glue Boost as a finish on about 10 pens and razor handles.Everything has gone great. Really good product. But yesterday I ran into a problem. I turned a razor handle out of Zircote,sanded to 1500 and applied a coat of Glue Boost thin . It turned completely white. ARRRGGGHHHH!! sanded off and ended up using 4 coats of Pen Plus. My thought is that the oils in the Zircote reacted with the GB . Any other ideas as to what could have caused this would be welcome. Thanks for listening to my gripe.
