I've heard of people using Epoxy to repair pitted forks but have not done it myself but don't see why it would not be effective.
There is not alot to loose, you either repair them, get some new forks, or wreck your seals.
Someone elses description bellow:
You can do a bodge repair on pitted forks that is very effective although not all that aesthetic.
Firstly, clean all the rust off, down to bare metal, make sure you get rid of any flakes of chrome and scrape the rust out of the pits with a stanley knife blade.
Degrease the stanchions thoroughly using a solvent, you must completley remove all traces of oil clinging to them.
Now get some Araldite epoxy resin, it is improtant to use the original slow setting stuff (now marketed as precision?), NOT araldite rapide which absorbs water and swells over time.
Mix it up and skim over all the damaged parts of the fork stanchions, try to use as little as will fill the defects whilst still having it standing a little proud of the surface.
Leave to set for AT LEAST 24 hours.
Now using progressivley finer grades of wet and dry paper, polish down the araldite 'till it is perfectly smooth and level with the rest of the chrome surface, finish off with a cream polishing agent like autosol then a wax polish.
This works, I have done it many times. The critical parts are 1) How clean and grease free you get the surfaces. 2) The amount of elbow grease expended polishing.
