Europa-List: Scuffing for grip

[Fergus Kyle <VE3LVO@rac.ca>]

Cheers,
        On the above subject, I just remembered someone advising me that to
scuff for max retention, Boeing instructed that the ideal test was whether
the scuffed surface would hold a lamina of water, rather than have it run
off or consolidate. It delays the application to wait for drying, but I
thought it might bear repeating?
Comments invited.
