Ospho isn’t applied and left on as a finish.    It can be used to convert rust to an iron.  In that case applying it is a different process than just etching metal with it.  I was etching the bare metal.  I spray the Ospho on and let it sit for 30 minutes or more.  When I spray the ospho I used a scuff pad to remove any light surface rust and it cleaned up all the welded areas on the control arms.  Once the parts sat for a while I rinse with water and a new scuff pad.  Dry the parts with a towel and blow them off real good.  Then I applied epoxy primer and let it tack up and then the color coat was spray.

I scrubbed all the bare metal with a scuff pad and ospho.   The scuff pad would have been enough to remove the light surface rust which wasn’t really anything at all.  The arms had just been sitting for a while the rust really isn’t worth mentioning.  The reason for the osph was to etch the metal or prepare the metal for epoxy primer.

Thanks for explaining the process.
Never heard of it before.
