I hate to tell you this but if you are just spraying the SWP product on
and then wiping it off you are only cleaning the surface of the metal
and doing very little actual phosphatizing. The key here is that you
said the SWP product was a cleaner and phosphatizer. This is probably a
fine product for cleaning but to actually put an iron phosphate coating
on the surface of the metal you must not wipe off the coating until it
"cures" and leaves a grayish film. On the other hand if you have excess
iron phosphate in recessed areas and runs under bolts and bolt holes,
you must remove this excess or you will have adhesion failure in the
future. It ain't simple.
Rubber gloves (not plastic or latex), eye protection and something to
protect you from inhaling the fumes is a MUST!

All the pros I talked to (many) direct me to a Sherwin Williams product that
phosphates and cleans at the same time. Its in a gallon jug and I spray it
on, wipe it off. I cant remember the part number as I am at home right now,
but it does a great job. You have to completely wipe it off and this takes
time and care to get in all the crevices. Key thing is to wear surgical
gloves while handling the parts and then use a good etching primer
afterwards. I am told that I can now relax completely and get to the repairs
on the parts whenever I have time since the metal is now fully protected
against the elements. Aside from that, I have all parts in a very climate
controlled building where its a constant 76 degrees with low humidity. I'm
happy. :) But then again I am no professional. I am very new to all this. I
do pride myself however on checking with people who DO know before I take
any serious plunges.
