Whilst I agree with what Splitpit is saying, in fact Novus used to issue a black spot tha you would stick over the pit whilst curing the resin. This kept a damp spot ready for pit filling. There are some times when I would C.U.P Usualy when the starbreak would have a legs that is open to the surface, this I would treat by laying on some Magnibond resin along the leg, placing a tab over the top and flexing from inside until full. I would then cure this break under pressure. As there is a good chance swinging the bridge away would suck some sir in. Now this way of curing would still leave the desired damp patch under the injector ready to accept the pit fill resin. Also I sometimes C.U.P those real big breaks that you get on truck screen as I have found removing the injector on a really large break with a big pit will allow resin to escape if not cured. Before I get jumped on I do not mean all the resin but enough to spoil the job. As I see it C.U.P is just another tool to be used when required.
