Peter Belgium Posted June 16, 2018 Share Posted June 16, 2018 After anodising my red color do not stay on the aluminum. With ordenery aluminum it is no problem. What I do: First I clean the parts with sodium crystals then rinse in demineralised water, than electrolyzing in 30% H2SO4 back in demineralised water, than in anodisingcolor for 40 minutes. Than it need to be boiling in demineralised water. But from the moment the part enters the water, the color washed away. What am I doing wrong and is it possible to color 2024T3?

Kent Ashton Posted June 16, 2018 Share Posted June 16, 2018 I see that anodized aluminum can be dyed Seems a little easier to clean with Metal Prep, prime with an epoxy primer, then paint. That holds up very well for me. Quote -KentCozy IV N13AM-750 hrs, Long-EZ-85 hrs and sold Link to comment Share on other sites More sharing options...
