Krissly, we are heading for a middle ground here
I don't mean to sound like this is any kind of attack or something, it is nothing personal. I am peeeeeed about how POR is marketed that's all. You see, POR in it's very own instuctions tells you to "scrap off (or something to that effect) the loose rust" as a preporation for painting with POR paint! That is what it tells you to do, just scrap or wire brush off, I forget the exact language. Then paint the POR right over the remaining rust! This is just
ludicrous! It is wrong to give people the impression that this is going to fix their rust. I will read on forums all the time how people are believing this crap! I tell you, it is just like the diet pills, if it is something a person WANTS to believe, really
WANTS to believe like they will loose weight without any work, they
WILL believe it no matter how ridiculous the statment is.
If you were to treat the rust proplerly with the metal treatment (conditioner) with acid to convert the ferris oxide to iron oxide and then prime it with a good primer (preferably Epoxy) then paint it would be much better than slathering on some tree sap, don't you think?
If you were to treat it properly, then apply the POR it would "do the job", sort of. But then, you don't need the POR at all do you? It is NOT the miracle "This is not paint as you know it" (right off the POR instructions) product. It is just not a special once in a lifetime product.
Let me put it this way, if you use a "regular" primer and paint system without cleaning the rust off, up against POR without cleaning the rust off, POR will likely win. It is a "covering" that is better than "regular" paint systems. But it is
NOT in anyway better than fixing the thing properly with a real paint system.
That is my point.
