Rattle can paint = rattle can paint to a lot of folks on this forum. It's one of those no-no's like using an other-than-GM made part somewhere. I could change my stovebolt name to RattleCanTheTruck, mainly because I like rattle can paint better than I like rust.
The basic function of automobile paint is to protect the surface, so the stuff you bought will do that if you get the metal good & clean prior to painting it.
I used some "appliance epoxy" (which was actually just an enamel) to touch up a bumper two years ago, just because I had some. It did not dry to the hardness I expected (because stove & fridge paint is tough), but the paint was still on there in July when I bead blasted it off. And it was still a very glossy white. It blasted off in the exact width of the spray nozzle (not it big flakes, so it seemed to have 'stuck' on the metal pretty good). Several spots where I dropped wrenches on the bumper had started little rust rings, so I wouldn't put it on moving metal on metal contact parts.
Wait until the air clears (the forecasted rain passes through) & the humidity drops- I seem to remember it stayed sticky for a long time like it didn't want to dry. That could be just because it looked wet for a long time...
