I've started making jigs recently and have read on a ton of places that ones with rubber have the potential to become damaged or ruined due to the possibility that any rubber used in them may melt under certain conditions. I'm aware of storing the jigs or the rubber with unscented talc. However, unscented talc has been difficult to find. So, does anyone have any suggestions on possible brands of unscented talc and places that it is easy to find? Also, are there other alternatives that can be used when storing rubber and/or jigs made with rubber?
