Hi, Rick. I Alodine all my aluminum bits before bonding, after first using the
Alumiprep wash. I've also taken to using it for my aluminum chassis work for my
tube audio amps I build before painting. It really makes the paint finish stick
like mad.
I get my Alodine from Wicks Aircraft or Aircraft Spruce, both USA suppliers. I'm
sure there are UK vendors, however.
Oh yeah, roughen the alu bits with the coarse side of a Permagrit tool before
alodining. You DO have a selection of Permagrit tools, don't you? If not, do
yourself a huge favor and get some. I couldn't live without mine. Expensive,
yes, but definitely a huge labor and patience saver.
