I used black CA to fill in the rivet rows.

The black color gives a good indication of your work progress.

The CA was sanded down using #400 and then #600 sandpaper. Then I went straight to a primer coat. The black CA sands down nice and smooth.

Another trick you can use with CA glue is to use debonder to clean excess CA glue from a filled joint. After filling the joint on my Ki-61 with black CA, I used a cotton bud moistened with CA debonder and swiped away the excess glue, leaving a much flatter joint. It's not perfectly flat and needs some putty to finish it off but it saves alot of time and surrounding detail by minimizing the sanding needed.

I use BSI Black CA glue and Great Planes Pro Debonder and I can vouch that both of these play nice with styrene plastic. Beware of the AK black stuff... I have heard that its stringy like old Testors glue. And the first debonder I used was Zap and it was junk... didn't work well at all.
