I am trying to repair a large pvc fender
with a small split in the end opposite the inflater valve. I tried to weld it with a small blow torch but found the pvc tends to either burn or melt away from the hole rather than seal its self. It is not pratical to put on a patch in this location. I was thinking of drilling a small hole at each end of the split and injecting some sealant
in such a manner that it would form a puddle on the inside. Then inject a small amount of air in the valve to force some of the sealant
out of the split. Then leave it while the sealant solidifies for 24 hours, and then see if it would withstand inflation pressure. Any ideas if this would work
? What sealant that would work
best? Any other remedies or pratical suggestions?
