I've just stripped down full clean and re-taped my slx tonight...
Been having a few problems in the last month with a dust like substance holding sections in and not running freely, i kept cleaning it once a week or so but never made much difference and after half the day it's holding sections in again

I lay out all the sections on the floor one by one and only two had stop tape left on it and the others were missing "mmmmm" is this what the black dirty stuff was jamming the pole up?
It's back together again and feels smooth but will it last

Anyone had similar experiences please?
