I have a nearly antique BMW R-80 that had a leak in one of the bottom seams of the tank. I got some sloshing sealer that is used by airplane companies to seal tanks on brand new planes as they are built. Should be good stuff, right? Weellll airplane fuel doesn’t have any ethanol in it. It is nearly impossible to buy auto fuel without 10 to 15% ethanol around here. I was not aware that the ethanol fuel would “eat” the sealer. SOOOO, now I have a tank with a thin film of worthless goo on the inside.
I did an internet search for info about POR-15, which has been discussed here many times. I don’t think this exact issue has been addressed though. The person I contacted said the company makes something to clean out the “failed sealer”. Then there is a process to go through to get rid of any remaining rust, and finally reseal the tank with a compound that they say is impervious to ethanol fuels.
Has anyone here had this sort of situation? Did the POR-15 product fix it? If not, what did you use?
Tanks, I mean thanks.
