Decided to start a new thread.
Many of my molds cast with collars bars etc... I know it is fairly easy to cut them off after casting and have tried a lot of things to blobk them off so I did nott have to mess with clipping collars. Having said that I have tried the foilowing with success but each has drawbacks. Really curious as to what others have tried and any pros and cons you can think of.
= Hi temp silicone caulk, works, is hard to remove and needs to cure overnight before casting. It a bit tough to remove
= Plaster of Paris, works, easy to apply, easy to remove. best to air cure over night before casting. Soak in water to remove
= Plumbers Putty, fast, does not last very long, easy to remove as it stays soft
= Bondo, fast, works well, needs care to remove and usually some dremel action. Realistically would call this semi permanent as it stays until you remove it
