There is cement on the market that claims this. It's called PVCGIT Clear PVC cement. -I'm a little sceptical and would like to find some and try it.
CPVC glue is specifcially formulated to glue CPVC pipe and needs a primer.
you cant remove primer. if its an eye sore for you . You can try to hide the purple primer by either panting the pipe or you could use clear primer next time. primer was made to clean the fittings and weaken the pipe so the glue would react to the PVC pipe. making one piece. thay make purple prime so city inspectors could visualy see that the plumber properly prepared the pipe.
You can use clear epoxy.
Super Glue's 'Original' will dry clear in that use.
PVC Primer and PVC glue
Prime it first with an autobody primer spray.
Elmer's white glue.
Glitter glue drys clear but the glitter obviously doesn't. The glue that makes the glitter stick fades though.
PVC glues will work on PVC type plastics if a primer is applied. This is a specialised glue for piping and MAY glue other items, but don't expect too much.
I wouldn't even try! There are similar cheaper substitutes available though. The Decopatch glue is NOT PVA. It is a glue-varnish that dries clear and waterproof so I wouldn't even try to make it. Don't forget to mind your clothes ... it doesn't wash out!
The best is Weld On 711 when used with purple primer.
Almost any craft store and many stationary stores sell clear glues.
