pre-primer etching?, anyone used Eastwood After Blast? Options

[jmitro]

My car was sandblasted to bare metal inside and out. I used Eastwood After Blast.....supposed to be a cleaner and also etches with phosphoric acid. Will be priming with an epoxy primer.

The problem is now there is a chalky white residue in many areas that has to be scuffed off. This is going to be a much larger time committment than I anticipated.

According to Eastwood, I should be able to prime without any further prep, but obviously this will not work.

Any suggestions about removing the residue and prepping for primer?

prep sol looks like a wax/grease remove, not a protectant against rust, so it won't achieve the protection that I'm looking for. And yes, I'm using wax/grease remover prior to priming but it does not remove the residue.

I'll check on the ospho information.

Thing that's frustrating is that Eastwood says after applying this, you can go directly to primer. NOT
