I actually tried this the other day. Might not sound appealing, but for you aussies out there, clag paste works really well. Now, call me naive, but I'm not sure what white glue is specifically. But if it's any relation to PVA glue, don't use it. I also tried it after the clag. Once dry, it turns into a sort of plastic-silicone-type substance. It will just peel, not sand.
