Giving off toxic fumes that can affect humans that breathe too much and those fumes will also fog/damage a number of plastics and similar materials.

Well, just about any glue has solvents. Just make sure and work in a well ventilated area. C.A. isn't problematic when it comes to vapors.

You should contact Nikon, they sell replacement rubber covers for the D300, as I recall under $5. re-glueing is only a stop gap repair, depending on the chemical make up of the glues they may react and come loose sooner.

Ihad this problem; I used Araldite Rapid, but you have to work quickly- it does the job though.

Rubber cement works also (yes the stuff you used to use in school and for paste ups)...put on BOTH surfaces let dry and then press together, same as using contact cement, plus easier clean up than others mentioned... just rub off excess with your finger.

I believe the same thing happened to my D90. The best solution is to order a new rubber ring. It costs about $10.

Loctite Super glue. But be careful, get it on your fingers and they get stuck, you will be webbed for years. Only thing that gets it off is acetone.

I used PLIOBOND an industrial adhesive to repair rubber on my lens and cameras without any problem just follow the directions http://amzn.to/1ScTqys

I would avoid glues like Super Glue or any cyano acrylic glues as they are very hard and brittle when they cure. This will tend to make the rubber itself hard and brittle, and the glue joint itself will tend to failure in a heavy wear area like that.

The Shoo Goo sounds promising as it would have to remain flexible after it cures (considering what it's designed for). The glue I have the most luck with in these type of situations is Contact Cement. It adheres to every surface I've tried and still has some 'give' when it cures so your rubber will continue to feel like rubber after the glue sets.

You can buy these rubber parts at amazon and on ebay. They have the adhesive tape already attached for around $20.00 it's by far the best way to go. Gluing with superglue or anything permanent may make removing them for repairs impossible. Bought mine off of amazon 3 years ago and they are stuck just fine.

I have used super glue for years on rubber and it has never hardened. Where do you get your facts ?

For $18 you can get replacement grips on eBay, they come with the adhesive strips attached -- just peel off the protective film and attach, no waiting for the glue to setup no worrying about glue getting where it doesn't belong. I bought these for my D300s and they worked great. See here:

Pliobond is correct, and sold at ACE and other hardware stores.

Have been using it on cameras I buy and sell for many years. Just follow the directions. It's much like a contact cement that is removable.

I also do this, when the grips are available. They come with double sided tape cut to fit, peel paper off the adhesive and apply.

Very good experience with these from eBay.

These rubber grips don't just come unglued, they expand and have a tendency to exude an oily substance that contaminates the surface of the rubber. Both surfaces need to be completely clean before any glue will stick. I use Acetone to clean the surfaces thoroughly and then glue with a marine quality contact cement or, a bonding agent called Plio Bond. Please don't use Gorilla glue. It doesn't work all that well and is tough to clean off when the grips are replaced.

If the grips are stretched, they'll need to be replaced. I can sell you what you need or you can buy the grips directly from Nikon. (Recommended).

These come with adhesive tape already attached. Just peel and stick. Again, make sure the camera surface is clean beforehand. You can use alcohol and a Q-tip. This is a little slower than Acetone but works well.

Before you send it in for an overhaul, check the shutter count at this site. You'll need to access the last image shot with your computer, but it will give you an idea of how many shots are on it.

Shutter lifespan for the D300 is around 100,000. If the numbers are close, contact me by PM about an overhaul. I'm a professional tech and do these all the time.
