Not quite Morgan related but I thought it might be beneficial to all.

The discs on my V70 need doing due to corrosion. Now, occasionally my cars sit there for perhaps a month as I don't always need to drive around. This must exacerbate the fact I keep it on road in all weathers.

Further to the 'cleaning my car' thread, I have noticed products such as this:

If I were to have new discs put on I wouldn't want them to corrode within a year. Would this work? Any ideas?
