Make sure to seal the tank first then paint!
I use por15 and vinegar!
The vinegar might eat away at the jbweld but donβt worry to much about it, i usually get away with sealing the tank the reapplying jbweld! Use the quick set jbweld youβll save a lot of time!
The por15 will expand so donβt be surprised if the pin holes look like expansion foam just sand them down! Two coats of tank sealer especially with jbweld is not a bad idea, it might save your ass from a really Bad situation!
