Do we really need to sandblast the frame

[Baby John]

Towed the frame out of the shop last night with the 4-wheeler, and soaked it down with degreaser and pressure washed the heck out of it two or three times. Obviously there was some scraping and re-soaking between pressure washing to get the gunk off the really greasy spots, but for the most part the frame is rust free. There may be some small areas with very very light surface rust but nothing a wire brush wouldn't handle.

We were planning on taking the frame to be sandblasted, but it just doesn't look like we'd benefit at all from that. In fact I'm thinking it may be detrimental because I've seen some pitting develop after sandblasting.

My question is, "if my frame has no rust, would there be any real need to sandblast?". Also, I'm worried about how the engine degreaser is going to affect the adhesion of the frame paint. How do you guys recomend treating the metal just prior to spraying the frame paint?

FWIW, I am planning on using the Eastwood frame paint.
