   We are having some difficulties gluing to black anodized aluminum; most   
   likely caused by the sealing process that closes the pores at the end of   
   the anodisation process.   
      
   I'm looking for hints/tips on what type of anodisation process and/or   
   glue to use:   
      
   - What type of acid do you use for anodizing? Standard sulfuric acid   
   anodizing (Type II)?   
   - What layer thickness do you specify?   
   - What kind of dyeing do you use? Organic dyes or electrolytically   
   deposited?   
   - What kind of sealing process do you specify? (hot deionized water?)   
      
   - What type of glue do you specify? (Epoxy / Silicon RTV?)   
   - Any particular recommendation for a brand / part no.?   
      
      
   Many thanks!
