I'm unfamiliar with OSPHO rust stopper. Keep us updated on how it works.
Ospho is great stuff, I've been using it for years. It works well in areas where you just can't get to with tools. Spray it on and let it dry, surface rust turns black and becomes a paintable protective layer. I usually pour it into a spray bottle and squirt it on just about everything that's going to be hidden behind another panel, or might not get completely covered when I paint.

The tank is just a regular old stock tank, typically used as water troughs for livestock. I've been searching the many classified ads for quite some time for a deal on a large enough tank to fit the sedan's monstrously large fenders and doors. The seller had this one listed for cheap, so I figured I'd better just scoop it up while I had the chance. Molasses works great for getting into the wire edge of the fenders and down into the seems of the door skins where they wrap around the inner structure. Pretty sure I can get the running boards in there, too! I'll throw as much into the tank as I can and let it stew for a couple weeks, then clean it all up and shoot some epoxy primer on everything. This was a must have item to keep myself to my schedule for the build, so I'm pretty excited to have finally located and aquired it.
