This was on my list to also ask about (and maybe should be in a different thread), but in watching a lot of the alodining videos it seems pretty straight forward of 3 different baths to dip the material into. I was thinking I would like to do all the small parts in the Alodine and then treat the joining surface with the Self-etching primer on the non-alodine treated joints. Effectively we would have one component treated with alodine and the other component with the self-etching primer meeting up. I know dissimilar metals/materials sometime can be an issue, but would this be an issue doing it this way? I just don't want to do the alodining on the big parts. Anyone have any thoughts on this process?
