Thanks, info much appreciated. I did have a bit of an experiment using the 600 wet and dry (just found it in the garage and thought it would be ok), but wasn't sure whether I would rub some of the carbon away, so didn't go any further.
I'm taking it with me to Norfolk tomorrow, will ask the price of a full rebuild before deciding whether to do it myself or leave it to the experts. I think it should be worth doing, its a zziplex B14, don't know much about it but was told they are quite rare and a good backcasting rod.
Another question, if I did go for a rebuild, do they usually go through the process of removing the old cacky varnish, and re-apply some more?
