Fixing Pin Prick Holes in PVC
I've finally got around to looking into why our port side rear tube section goes soft over several days and found two minute pin prick holes on the base of the tube, just forward of the seam joining the cone.
This is an area that contacts the water whilst going along, and also gets spattered with mud etc from the wheel of the trailer so I guess it could be from grazing something in the water, or from sharp debris kicked up by the tyre on the trailer?
Anyway, I wondering what the best way to fix it would be. As you can see, the leak is very slow and the holes are practically invisible to the naked eye.
Would a patch be the best way, bearing in mind it will be contacting the water and liable to peel. Or can I seal/coat the holes in adhesive/solvent and avoid having to use a patch. If so, what would be the best way? Presumably let the pressure out the tube first?
The material is PVC.
