I am looking to determine how to reduce the amount of visible fingerprint appearing on an anodized sheet of aluminum with a radial brushing pattern. I have been told previously that it has something to do with my sealing process however I was looking for something a little more precise. Is there a specfic sealing solution, sealing temp and sealing time I should be using or if there is another step in the process I should be altering.

I would like to thank you all in advance for any assistance you can offer.
