If your in the burbs Autobarn do a cavity protection spray for about $15.
Apologise for picking up an old thread.
I've picked up a new frame (Colossi Low Pro - 6061 Alu) and I've been wondering about putting frame saver (fish oil) through it. I know that it's definitely a recommended process for a steel frame, but what about for aluminium? Necessary?
Awesome! One less thing to worry about! Appreciate the help.
