I have also used Extend over the years and it's a good product. According to
the POR-15 literature, it works a little differently. It doesn't "convert" the
rust as Extend does, it simply acts as an impenetrable barrier to moisture and
oxygen, unlike other paints. Of course with no oxygen available, iron oxide
(rust) cannot form or spread. It is cured by moisture, not oxidation as most
other paints are.
Having said all that, I have never used POR-15, but I do intend to try it on my
frame soon.

Subject: POR 15 vs. Extend
While we're on the subject, what's the difference between POR 15 and the
stuff made by Loctite calle "Extend"? I have used Extend for years. It's a
milky sort of paint that complexes the oxide and turns black when dry.
Pretty durable of its own accord and can be painted over if one wishes.
They sound very similar, including the price.
