Bare Metal Questions

Please tell me next steps, I was a bit premature in sand blasting and soda blasting the body of my project car. Blasting was complete just after Thanksgiving. Main body was sand blasted, fenders, hood deck lid, and doors were soda blasted. Since we got her home we have completed the rolloing chassis, but the body is now covered with surface rust. What's next? I saw a post about using Naval Jelly and steel wool, will this do the trick?

Also, the sandblasted body has a much rougher surface texture that the panels that were soda blasted, do I sand the entire car to match the texture of the panels or will the epoxy primer fill in the rough spots?

Thanks in advance for any guidance you can provide.

You should have put on epoxy primer right away......you are going to have to strip of that surface rust. It may wipe off with naval jelly, then wipe that off with laquer thinner.......and prime with epoxy right away.....inside and out.

you can break this down into steps, trying to remove the surface rust on the complete shell and prep and prime at one time may be a challenge. I would do the roof first. then quarters, etc if time is a problem. The absolute best time to prime something is asap after blasting. How bad is the rust? will a scotchbrite remove it? Bob

While I agree that the best time to cover is right after blasting I purposly didn't do that with my project because I knew I had a lot of welding to do (patch panels, modifications, etc.) and I didn't want to deal with burnt paint. When I finally got to the point where I wanted to prime it I had 4 years worth of surface rust but I found that "Oxisolv Rust Remover" worked very well without much effort. Follow the instructions and you end up with a zinc phosphate coating in place of the rust.

OK Thanks, I'll take care of the surface rust and get in in primer right away. What about the different texture of the metal from the two different types of blasting (soda vs. sand)? Hood, deck lid, and doors were soda blasted and are much soother than the main body that was sand blasted. Will the primer take care of these differences? Thanks again.

Go to your local automotive paint store, tell 'em what you got and they will provide you the appropriate high solids primer. If you ask 'what brand?' here you are likely to get as many opinions as there are brands, you basically have to make that call yourself.
I had a similar situation as yours... ended up using "Evercoat Feather fill" high solids black primer. I loved the stuff, its like sprayable bondo. Found that it seems to have its own built in 'skim coat'. After you sand it, it turns gray. Note that this was my first attempt at a quality job and that I am your basic amateur.
