Sun. What's that?!:grin:
The Seiko Strap Rejuvenation method was first brought to our attention by Guy in this thread:
I experienced excellent results using Guy's method on a bunch of older, well worn GL831s and they turned out much better than I thought ever possible. Guy's method is good common sense as Silicon Grease is formulated to be used for rubber O-rings and is used by almost all watchmakers to lube caseback and bezel gaskets. As the V1s were graying with a gooey surface and looked identical to the older GL831s I thought I would try Guy's method once again.
I have 4 different types of Silicon Grease and decided on a lighter, thinner mixture. Application was same as before; It's very simple and easy. Start with a good scrubbing in soap and warm water, dry, silicone grease applied liberally, let bake in the sun to soak in, wipe down very well, more drying in the sun, final wipe down. Finished.
All the straps are back to looking just like new with a dark black shiny surface. Not tacky or sticky at all. Very smooth to the touch. They also feel more flexible than before.
