will this internal sealant work if there is a little water in the tubes?
Cheers and thanks
The O'brians stretch tape stuff will not hold and can potentially tear the topcoat off the hypalon.
This location is a very high wear area.
All patchwork must be completed while the boat is uninflated.
Paul is correct, water will dilute the internal sealant which can make it work poorly. Remove your valve and utilize a shopvac to remove the water.
They work fine on ribs if you can locate the sealant to the leak. However, if the tubes are still ran underinflated, the oscillation of the tube will continue to tear the seam apart and will eventually displace the sealant. Eventually the entire seam will blow open in a magnificent fashion.
