I think it is time you went into business! DTI'S-R-US. You make a superb job of them, and there is nowt worse than trying to get a good reading out of a sticky dti. I'll send you some of mine if you like, but really I haven't got the bottle(or maybe the eyesight) to dive into them> You could at least write a book called "Cleaning and Repairing the DTI"
Well done again!
