I'm doing the desloshing in my RV-4 and here and there a chunk of the proseal that was over a rivet on a rib is lifing and pulling off. I dont think the inside of the rib where the shop head is located was scuffed (not sure if plans call for it even).
Looking for advice from those who have fixed leaks in tanks or know what the standard procedure is for adding more proseal. I'm cleaning the slosh out with MEK so I plan to use it to clean before applying any proseal but I'm not sure if I need to scuff any existing proseal or not and if so, with what (grit sandpaper or scotchbright).
