Help with sanding after media blasting.

[sick472]

Whenever I have sand blasted body panels...I just wipe them real good with lacquer thinner, let fry, and shoot them with primer (give that they are rust free from blasting). That rough texture is fantastic for good primer adhesion. Any pitting from the rust can be given a few more coats of primer and then the all the primer can be sanded to smooth it out... Then I go after any body/dent work. Seal the all the blasted steel and then work it to get the dents out.
