Hi Matt,
Yes the SA was based solely on the OD only so you have a good point there for sure.
The part didn't turn gold/yellow but it did have some kind of residue that I noticed washed off in the de-io rinse before dyeing.
Someone else advised that if you heat the dye to anything above 50°C it would in fact start the sealing process?
Lastly I'm think the aluminium is 6000 series but not 100%. Could the residue actually be smut? If so is there a way to overcome this?
Thanks again
