It would have been better if you primed and then did the filler work but what you've done will work OK. The epoxy primers used now days effectively seal the surface so no air can penetrate and create rust. Etch primers are yesterday's technology.

Once you have the surface stripped spray a good coat of epoxy primer on before doing anything else. Then do your filler work over the primer (just remember to scuff it really well first. Fillers will attract moisture from the air so thats why you epoxy prime first. With filler over bare metal it can actually allow moisture from the air to get to the bare metal underneath. I wouldn't worry about what you've done so far as long as you don't wait too much longer before getting a good coat of epoxy on it.

I totally agree with Centerline, epoxy then filler then epoxy then primer surfacer for the absolute best results. You must be working in an extremely humid climate. Most of the time the flash rust can be removed with a red scotchbrite before you apply your primer. Epoxy should be applied to a metal surface that has been sanded with 80 grit for best results but I've prepped sith as fine as 180 with no problems just be sure your paper is new and sharp- old worn paper will simply polish the metal's surface and not provide the scratches necessary for good adhesion.

62Galaxieguy,

Are you rebuilding a 62 Gal? I currently have a 62 Gal that I'm working on. Have any pictures?

Mike,

Looks like it's going to be a good project. I lucked out and bought mine from my uncle. I put a pict in my gallery. It doesn't need a lot of work, I put NOS upholstery in and when I can afford a good paint job that will be next. My uncle waxed it so much that the paint is worn through in spots.
Bob
