Paul, there was an intensive discussion on the Chevelle list a while
back about the same topic, and some of the following points were made:
1. You do not want to apply POR-15 over non-rusted metal as a rule. It
seems to work best when activated with a solidly adhered rust coating.
Hence it's name "Paint Over Rust". If you have a freshly blasted
surface, you might want to "flash rust" it with a spray of water. Make
sure that loose rust flakes are wire brushed off.
2. Some folks have noticed that it discolors (turning yellow-y) in areas
that are subject to sunlight. Underneath a truck on it's frame is
probably OK though.
3. There are mixed opinions as to whether you can effectively paint over
it. Reports of paint bubbling and POR-15 peeling were heard.
4. You don't want to get it on your skin or in your hair during
application. Impossible to remove...it has to wear off.
I also was on the fence about this product, and have since placed an
order with Eastwood for their "Corroless" which is a product similar to
POR-15. Eastwood claims you can paint over it. I will let the list
know about my results, short-term at least.
