Very nice display. I am curious....How do you keep the rubber from hardening and rotting?

Do you have to do anything special to preserve all of your artifacts?

You are left at the mercy of the rubber!! there is pretty much nothing you can do. However the orignal techinque used when packing rafts for example was the use of talc powder for moisture purposes but is a bit messing. The best thing is climate control. The reason we find stiff items is because in its lifetime there were in poor/dramatic climatic conditions...moisture, heat etc.

But also another factor that plays a role is the type of rubber used. For the mnaufacture of life rafts and preservers or anything rubber for that fact there were various forumlas utilized by manufacturers. Sometimes in production runs they were using what could be considered "experimental" formulas, this was all in attempt to graduate past the use of natural rubber or greatly reduce the use of. Some of these formulas stiffened up and cracked only after a few months in service. Some of these rubber items in collections could have been "lemons" from the get go! Basically its all dictated by climate control and once its starts to deteriate ...its over!!

Years, and years ago I passed on an original MKI life preserver because it could not be displayed on a mannequin, it was too stiff! I really should have picked it up I guess, it was only $20..
