Don't worry about the holes, the amount of corrosion you will get in
thin sheet is about zero, but you must assemble all joints with zinc
chromate jointing compound (Duralac), that will definitely stop any
corrosion in the holes and around the bolts etc.
Why not drill all the holes in the peices before you send them off for
anodising? Or alternatively use the tried and test method of coating the
parts in zinc chromate primer, this can be obtained in aerosol cans.
