<VV> Epoxy Glue (very little Corvair content)

[JVHRoberts at aol.com]

PVC does weird things to epoxy. The plasticizer necessary to eliminate  
brittleness in PVC migrates to the interface when a non solvent adhesive is  used. 
PVC pipe material is engineered to be solvent welded, not bonded with  things 
like epoxy, polyurethanes, silicones, polyesters, etc.

One  other thing that I have found that J.B. Weld will not stick to is PVC  
pipe.  Tried on several occasions repairing 2" PVC joints on pool heater  
(solar panels, on roof), and had had no luck with it.  Water (under  pressure) 
leaks right through where the J.B. Weld was applied. Anyone have  similar luck 
with PVC or was there something I did wrong applying it.  I  cleaned the pipe 
real good with Lacquer thinner before applying it.   Still great stuff.  I use a 
lot of it doing various repairs on my  Corvairs and other projects.
