No Hypo on PVC--you can use PVC glue on Hypo, but not Hypo glue on PVC.
Aso for removal--defalte raft and use a $14.99-19.99 Harbor Freight Tools heat gun with some channel locks / vice grips to heat and slowly pull off. Go slow, heat slow, dont rush!!
On the reglue--clean off all the old glue, clean with Toloul, resand it--remove ALL dust. Put on a VERY thin coat of glue--let dry 24 hrs. Repeat--let 2nd coat dry 24 hrs. Then use a lint free cloth to wipe toloul to "re-activate" the glue on both ends. Add d-ring to INFLATED raft and press as hard as possible. After rolling--deflate and roll the hell out of it all with a rasp or other item.
The 24 hr periods really allow the glue to properly set up for a high stress item like a dring. Patches are not some much of an issue. Foot cups also really do well with the 24 hr thing!
