WTF, WTF, WTF!!!!
It all boils down to preference and preparation!! From my experience and I hate painting, stuff we used on DOD work was fantastic, yellow zinc primer and polyurethane paints, they resit gasoline ,oil,diesel, battery acid and other chemicals!! I also used this other sealant, we knicknamed Grey goop that was used around various openings (smelled like rotten eggs) resisted all the above when dry and was still flexible ! 2 part sealant! Went together like Peas n s! Thats all I got to say about that
