Reply To: Gas Tank Sealant

Do not recall the names but I have used the slosh and seal sealers for years. My first time was on a Johnson A 25 , so similar to your tank style, about 40 years ago and it still works. That one was a yelliish green color and I have also used red color ones. Take out the filler cap and the shut off valve use something to plug the outlet that will not hurt the threads. Have the tank as clean as you can inside and dry. Put your filler in and tape the opening. Slosh it all around a few times then pour it back into the can and give it a couple of minutes to drain. Then let it dry. I will normally give it at least 2 coats
