Ive tried ALL the sealers, leak sealer, spray n seal, mighty seal... and Flex Seal is BY FAR the BEST! Not just cause they are the original but it goes on smooth and coats great. A few coats and the job is done! Seals out leaks and also coats protect the surface from weather, rust, corrosion. I bought that rustolium stuff, it was little cheaper but it didn't work! I returned it. FLEX SEAL is the best.
