Painting Over Ospho

I just signed up to you guys forum. It looks cool. I have been searching the net for a specific issue I am dealing with. It is with the use of Ospho rust treatment. My pet car I have stashed is a 73 Dodge Challenger Raylle 340 4-speed. It has been around here for a long time and I am retired so I have been taking time to work on it. The car has original paint and of course a good part of its life it has been outdoors. There are some areas with surface rust, some heavier. In the past I have applied rust converter and primer. Some areas now have minor rust coming through. The car is always in the garage now.

The specific question is I sanded the areas down that indicated rust bleeding through and applied Ospho. The problem that arose is that where Ospho has contacted painted areas (some non-original rattle can stuff too) there is a tacky residue that does not completely dry. I want to re-coat the areas with Rustoleum primer to continue to preserve the metal but I am not sure what to do with the sticky residue. The surfaces prior to application were completely free of wax and grease. I scrubbed it with Dupi- Color wax and grease remover. What should I do with the Ospho residue on the paint prior to applying primer? I am very reluctant to use water to remove it.

It sounds to me that you did not wipe up the Ospho when it came in contact with the painted areas. I use Ospho all the time on my 1941 Ford project. Did you just try to wipe off the tacky residue? Did you wipe the the area down before you first but Ospho with any thinner or cleaner? I have used Rustoleum primer on my frame and in spots that were not dry I got orange pill. I was dry to touch but not to the primer. Hope this helps you. You have to remember Ospho is clean up with water.

RE: Ospho over paint

Thanks for the reply. Everything was super clean and wax free when I put on Ospho. I was not in a hurry to wipe everything down, as I wanted the anti rust reaction to take place on surface rust ant pits. The areas were surrounded by paint so I did not have much choice but to leave it on the surfaces. I just need to figure out the best way to deal with the film before applying primer.
