Yes from memory (it’s about 2 years since I did mine) it comes as a three part kit. Cleaner/degreaser, metal prep, then the actual sealer. It took a while to do, again if memory serves me correct but it all did exactly what it said on the tin, so to speak. Like I say it definitely worked, I left my tank sat on some wooden blocks in my old works for about 5 days with some blue blotting type paper underneath it. Not the slightest drop came out 👍
