The question is: does POR-15 (expensive compared to other
anti-rust/anti-corrosion protectants) work in 5, 10, 20, or even 30 years as
claimed? "It works well", you wrote, but how would you know that? The
pictures all look very pretty, but don't they almost always do after a coat
of fresh paint? Also, the requisite meticulous pre-coating preparation is
daunting to say the least.
Don't get me wrong. I'm all in favour of a good anti-rust protectant for my
car, but I think POR-15, impressive though their claims are, may turn out to
be another disappointment. POR-15 was introduced in ?1958. There is
another product, more recent and claimed to be superior: it doesn't need
scrupulously clean metal for this formulation of isocyanate to work, so less
scrubbing away of the existing rust is necessary. It is called Rust Bullet.
