One word of warning. In most cases your sanded body filler is not going to be level enough for your car to be ready for paint. Since I have not seen your car I have no right to say it isn't but...... I would have doubts.
John, after sanding my filler I'll shoot a single coat of epoxy to seal it in between coats of epoxy. This is because I'll most certainly have sanded through to metal in some areas. Then, within the 7 day recoat, I begin with 2k.
To reiterate, yes, I see every place there is filler and this is normal.
