You need to fill the voids with Interlux Watertite or an epoxy paste such as West System epoxy mixed with colloidal silica. These adhere great and have the consistency of peanut butter and will not run or drip.
You need to do your filling first.
Your pictures show lots of little bumps which are voids-in-waiting. If you are going to repair this bottom you need to remove them also.
The right way to fix this bottom is to have a professional use a bottom peeling machine to remove the gelcoat and whatever underlying material have voids, following which someone (probably the pro) replaces same with new material, except your five coats of Interprotect substitues for the gelcoat. This type of fix is expensive...think $150-$200 per foot.
What you should do is just leave the bottom alone, repaint and enjoy the boat for a year or two. Then kick the problem down the road to the next owner.
