Due to the recent controversy over the suface grit of the dynamo,4000 or 1000, I emailed Lane 1 for an explanation. Here is their reply;

Ron,

Thanks for checking out our website, hope you've enjoyed it. There are 5
steps in finishing the ball. Each step is 25 seconds going from 50
micron(240 grit), to 30 micron(400 grit), to 20 micron((500 grit), down
to 5 micron(1500 grit), then a 4000 abralon on the last step. But, in
our opinion, either the 4000 abralon pads are not fresh or there's not
enough time to get a true 4000 finish on the ball. So to answer your
question, it's probably somewhere in between. If you have any further
questions, please feel free to contact us again anytime by e-mail or
phone 1-800-Lane No.1 (526-3661). Thank you.


Hope this helps

Ron
