Sandblasting paint prep

[Bubblee]

What is the procedure to prepare a part for paining after sandblasting? Should it be washed off with spirits or MEK before applying paint?

Also, will sandblasting ruin threads? I'll put bolts on them anyways, but just wondering.

No hurt on threads and no touchy of metal. Blow off the paint part and paint. The material is the cleanest it will be once it is blasted. That was directly from a blasting shop by me that I've done work with.

Depending on your media, you may need to sand first to end up with a factory quality surface. I lightly sand everything with 80 grit to bring the surface down to a smoother end product, then prime, etc. Do not wash with either of the products you mentioned, there's no need, and they can have a negative reaction with the paint.

i'm with texx on this 1. don't touch it w/ bare hands. just blow it off good, wipe it down w/a tackrag( preferably blue because it has less glue) spray it w/ epoxy.
