All, I had cracks in my airmatic on the front struts, After using a sealer called Captains Tolly's Creeping Crack Cure which I use on my big boat, It has the density of water which seeps and fills the leaks.
I did the following, First I used it on all the cracks, you will actually see it start to seep let it dry, Then do it again let it dry, and on the third time it wouldn't seep as much.
..I couldn't believe it, it stopped all the leaks, I checked it using the soapy water method.
It will dry to a hard like plastic, available at West Marine, Wallyworld or Camping World cost about 8 bucks.
It has been NINE months and still no leaks.
