The Cortec product we're talking about is VpCI 373. Among the properties
listed on their website a * Excellent replacement for chromate treatments. *Good adhesion on surfaces which are difficult to adhere to. * Multimetal protection * Excellent primer for aluminum * Conforms to MIL-P-15328D ....and etc. I guess I should have given a more specific URL. Try this: http://www.cortecvci.com/Publications/PDS/373.pdf |

These are both promising products, but they are very different.
I've done a fair amount of research on the least toxic ways to prep and paint aluminum, and I have never seen anything like Prekote. It's not a paint, and it's not a conversion coating, it's more like a detergent with a residual film. Note that the scrubbing is not to "penetrate the pores", it's to mechanically break down the existing oxide coat. I plan on trying this on my long-term exposure test piece. It MUST be top coated with a true primer and presumably a finish coat. The Coretec product looks like a waterborne version of long-existing "Wash Primers". It's closer to a paint product, in that it forms a "cured" film. A nice, low-impact product, but it's not as revolutionary as the Prekote credibly seems to be. Thanks to both of you for sharing these leads with us. |

I just made arrangements to get a gallon of Prekote to test. I'll
post my experience here. Pantheon is interested in the Experimental airplane market. Craig |
