What do you mean exactly? Was the complete coating swimming away
w.o.w. the stuff did not stick to the alumunium? This sounds familiar
to me: when I did the first trials with bromoil on alu, the same
thing happens. I used the Klaus Pollmeiers' beer-solution' as a
primary coating and that was the thing to do. If you don't find it in
the archives and you can't wait for Judy's PF#9 let me know.
