Re: Starting a G-Shock Collection... Slippery Slope?

How do you keep the strap from 'melting' or turning sticky in the long run? This is a common problem I hear but can't be too dry either if not the resin will crack very fast right? Plus Sg is too humid anyway. Anyone have ideas?
I used to collect designer toys, the kind made from vinyl. And that "melting" and "turning sticky" issue has been discussed at length on the toy forums with no solution. Some people recommend putting talcum powder and others recommend keeping the object out of the light and in their boxes.
However ONE thread a long time ago seemed to make sense and may shed some light on our strap issue. One poster on one of the toy forums claimed to work for a plastics moulding plant and he explained it thus:
A chemical called a platiciser is added to the resin to make it supple. it's what makes a plastic a plastic, if you know what I mean. Over time, this plasticiser will degrade and outgas from the plastic/vinyl (ypu'd recognise it as the smell of fresh plastic), leaving the surface that's exposed to air a sticky mess. This apparently is part of the natural degradation of that kind of plastic and there's nothing that can be done to prevent it. Though heat will accelerate the chemical process (like we learned in primary school), it's pretty much unstoppable.
I may not have remembered all the term accurately and I daresay that I'm paraphrasing liberally. But the gist of it is up there. Sigh... got several 400% Be@rbricks from the early days of vinyl that are stickily standing in my display case at home. Can't sell them coz no one will buy a sticky Be@r. :p
