Why don't you contact the people who make POR-15?
POR-15 also makes a stripper that works on other tank sealers, maybe it will strip their own product?
Their web page says this: "For those unfortunate customers who have had bad results from other inferior fuel tank sealers, we have developed these all new "HEAVY DUTY UTILITY & CYCLE TANK REPAIR KITS."
They feature everything found in our regular UTILITY & CYCLE TANK REPAIR KIT, PLUS a quart bottle of our famous Tank Strip to first remove that inferior coating that failed you."
