This may sound a little weird but bear with me & it does work.
Rub down the pitted parts with fine 1000 or 1200 etc paper wire wool or any other fine abrasive, buy silver coloured nail varnish & fill in pits & wait until dry rub down again & stand back & admire your work. Try on the non swept area first so you are happy with cosmetic side of things then do the lower part. Take your time you will be surprised at the results & as the varnish is quite hard lasts a long time. I have done this as a temporary repair many times & puts less stress on the seals due to no sharp edges.
Also to help you could apply some light silicone grease or rubber grease to lube the seals. Adding gaitors will also help stop corrosion in the future.
Hope this helps. It is cheap & the varnish lasts for ages. Ask a lady friend which is the toughest varnish as in which lasts or difficult to remove as some of the cheaper ones are better for this purpose.
