I have been doing the Prekote scrub + Akzo for a while now with good results. In looking to be more efficient, I’m wondering - What is the difference between etching with Alumiprep and scrubbing with Prekote.
Prekote is just a special chemical that thoroughly cleans the substrate, the 3m scrub makes it easier to bond the primer.
But isn’t that what an etch does as well? I’m wondering for all those small parts and flanges that are a pain to scrub, would the etch be enough?
I’m wondering if just doing the etch is good enough? I don’t live in salt water environment but I will continue to prime. I’m all for the epoxy primer because it holds up a little better when assembling compared to the etching zinc chromate aerosol options.
Thanks!
