Hi,
I have been anodising small plates with your black dye. I have had some good results with a nice deep black, however I am finding a lot of my plates are coming out with a 'sooty' matte deposit once sealed. This does wipe off but the underlying anodizing is a different finish to the unaffected areas, which leaves my final surface a bit patchy.
I've been applying wax to finish the plates which helps to disguise the marking a bit, but it would be good to get a decent finish to start with.
Any ideas what is causing this?
