In my case I built the tanks and they have never been sloshed. Do I just make an entry in the aircraft log book as to complying with the service bulletin and note the tanks have not been sloshed?
Back when I built my tanks, Slosh was RECOMMENDED. My tanks have white slosh. (White is Alcohol resistance. Yellow is NOT.)
I just did the inspection they called out in July. Over 2,540 hours and no slosh problems. I did scuff the tanks before applying ProSeal and slosh.
I have seen slosh come off and ProSeal leak when the tanks are not scuffed before applying.
