Base coat issue after clear coat

The attached fender is from a 1952 MGTD. My first go around had solvent pop and I wasn't real happy with the clear coat so I sanded the clear over with 320 grit and ended up sanding through the clear to the base in the area seen. I then figured it would be best to just go ahead, start over and re-base coat the whole thing. What is seen in the picture is after four new applications of base coat. Why would this one area of original base coat be showing through 4 new layers of base. Should I just re prime the one area or start over AGAIN with prime, base and clear?
Thanks for helping
Paul

If you sand through the clear, you have to prime the area, because base and 2K clear act very differently when coatings are sprayed on them. You can even get wrinkling around the clear edge if it's too fresh. It kind of looks like the clear edge was trying to wrinkle just slightly, though it's hard to tell.
 
yes and in addition to what crash said you can also see all the solvent pop. paint doesnt like to bridge over a void. solvent pop, when sanded opens up all those pores which you cant really just base over. you need to reprime the area to fix it then rebase
 
Thanks guys. One additional question. The non-issue base has now set for over a week so I will be scuffing everything in prep for the spot repair. Is it your recommendation to apply three to four layers of base to the spot and one more to the entire fender? Is 320 a good grit for the entire fender in prep for the clear or should I be using something like 800?

Are you planning to base coat the entire fender? If yes don’t sand the base coat, if you sand it you will need to apply 2 more coats of base before clear.
