Sand blasted my front and rear diff housings, cleaned them up inside and washed with soap/water and they flash rusted as they were drying. I should've known better (and actually I did). What's the best way for me to get rid of the rust? Blast again? Scrub with steel wool? I'm going to be using an epoxy primer and then a single stage polyurethane enamel.

Do not use steel wool, it leaves traces that will rust.
Try an Evapo-rust product, or phosphoric acid to dissolve the rust.
Use an acetone rinse/wipe immediately after cleaning the rust off.

Any solvents should be applied PRIOR to blasting. After you blast, you should blow off the dust with clean compressed air and epoxy prime as soon as possible without touching any of the surfaces to be painted.

You'll have to sweep blast it to remove the rust. It will only take a second.

Thanks! Damn...learning stings sometimes.

I'll usually just bite the bullet and have whomever is blasting the part go ahead and epoxy prime...just for this issue.
