FWIW, I recently started having trouble with the one I bought back in 2001, after I got thoroughly frustrated with trying to keep the possibly original starter going on my TR3A.  (It failed twice in a row on long trips, first on the way to VTR 2000 and then on the way home from 2001; both times over 500 miles from home.)

But after disassembly, I don't believe my problem was corrosion.  The top level problem was that the connector to the solenoid was no longer snug, and would sometimes not make good contact.  But I discovered that the motor bearings were also completely shot, and the armature was starting to drag on the pole pieces.  What little grease remained in the gearbox was dried and hard.  I'm not certain, but I attribute the bearing damage and grease condition to excess heat from the exhaust (which passes very close to the solenoid on a TR3).  I robbed the armature from another starter, someday soon I'll see if I can source replacement bearings.  I also added a sheet metal heat shield, which might help.

But it never snows here, and rarely rains, so in general I have a lot less trouble with corrosion than other parts of the country.

In your case, it might be worth trying to add some sealing against water entry (mine showed no signs of being sealed at all).
