I use Ospho and what I do is spray it on and let it dry , then before I shoot the epoxy I use a scuff pad and go over it . so far it has worked for me ...

Take Care
Earl

I tried the product on a few small parts and wasn't impressed, left to dry overnight it did leave a coating on the unrusted areas of the part that was easily scuffed off. Very limited adhesion benifits if any at all and very poor durability compared to directly applied epoxy IMO.

Now, if you're doing some work on an old farm tractor and using oil based primers and paints I'd have to agree it has it's place in this or similar situations.

Best results are with removal of all corrosion followed by the proper texture and cleaning of the bare metal surface and the application of two coats of epoxy IMO.

Beenaway2long, do like Barry suggested- if you don't like cleaning your gun just use a roller or paint brush to get the epoxy on the worked areas then when the panel is done sand her down some and spray on a couple coats. I've brushed epoxy on many times without problem, interiors and floors many times. Once the epoxy is cured it can be sanded easily before you spray. Bob

What im thinking about after reading a little about this is if it would work like this.. say u have a project where ur stripping the entire car to bare metal.. can u do each panel put this stuff on and let it sit for a while in bare metal and have it not start to rust? and then can u go over it with some 80g and then epoxy it? if it works like that then it seems like a decent idea.

Yes that's what I do. It keeps the bare metal from rusting than sand with 80 and spray epoxy.

from the ospho site:
"may cause dulling or peeling to some finishes" ( no warrentee emplied)
"test a sample area for epoxy or other coatings adhesion"
"historically it works best with oil base primers and paints"
"For marine and Industrial applications"

in other words...make damn sure you get all the iron phosphates and sodium dichlorate residue off before you apply the epoxy, especially on older steel sheet metal
