"Elmers rubber cement" doesn't sound like the rubbers will ever come off
Elmers Rubber Cement is totally fine. The rubbers come off easy. Elmers rubber cement, Best Test Rubber Cement. It is just rubber as glue so it is a lot like the old speed glue without as much of the VOCs in it. If you glued and they tested your rubber that day they might detect the VOCs but it does not expand the rubber the way speed glue would. So you do not get a real speed glue effect from it. In the US Elmers cost $2.50 for a 2 oz bottle, best test costs $4.00 for an 8 oz bottle and $6.00 for a 16 oz bottle. You can get Best Test at most art supply stores. Artists use Rubber Cement for a variety of things.
All the old glues that were not speed glue but were regular (not water based) glue, were really the same thing as Rubber Cement.
From a chemical makeup standpoint there is no difference between Best Test and Elmers Rubber Cement, and what you used to buy as glue from Table Tennis companies that were selling the non-speed glue glues. The only difference is it is not marketed for table tennis so the markup for that does not exist.
Just like you can just buy the chemicals that the Table Tennis companies put in the rubber boosters, Rubber Cement is the chemical of the old regular glues.
You can also get Speed Glue. There is a glue they use for tires that is Speed Glue. There is no speed glue that was better than this. I have to remember the brand. I will post when I see it at the tire store.
That being said, it is fine to use the water based glues. But they do cost a lot more than Rubber Cement. And a day after you glue with Rubber Cement the VOCs are gone and there is no speed glue effect.
