I have yet to use Prekote, so I'm certainly no expert, but as I understand it, it acts as a cleaner and etchant, so it would seem to be a substitute for the Alumiprep surface prep process. Although the literature talks about it as an alternative to Alodine, I don't believe it creates a chemical conversion coating of any kind -- I could be wrong.</p> <p>I'm with you when it comes to minimizing the chemical hazards around the shop, which is why I'm inclined to skip alodining altogether. If Prekote works as a good surface prep for some type of two-part primer, then I'll probably use it.</p> <p><a href="http://rv8.card-net.org/?p=33" rel="nofollow">Scott Card</a> is using a Prekote prep and AKZO epoxy primer on his RV-8 project, and seems happy with the results. You might want to get his opinion on the process.</p> Joe, thanks for dropping by.

I’m with you when it comes to minimizing the chemical hazards around the shop, which is why I’m inclined to skip alodining altogether. If Prekote works as a good surface prep for some type of two-part primer, then I’ll probably use it.

Scott Card is using a Prekote prep and AKZO epoxy primer on his RV-8 project, and seems happy with the results. You might want to get his opinion on the process.

I'm trying to determine if Prekote is a substitute just for Alodine 1201 chromate conversion coating or if it substitutes for both the Alumiprep 33 and Alodine applications. Have you been able to determine that? Does Prekote clean and coat?</p> After reading the MSDS on Alumiprep 33, I’m reluctant to use it around the home, yard.
