I have quite the experienxe with nikon rubber. I will say that public should be happy they dont make condoms. We would have a lot of unwanted pregnancies on our hands.
Ive done surgery on an n90s, f100 and 3 f5s. What i did was using eegular cyanoacrylate super glue And a dremel with a plastic brush tip attachment. Also a nail file or something to scrap the double sided adhesive tape they use.
Process was remove the old grip. Take it off slowly Not to stretch the rubber too much. Use the nail file to scrape and remove all the adhesive film/tape. Slowly pry it from under and pull it off as much of a big piece as possible.
Then take the dremel and scuff the back off the rubber piece with the rush attchment. Do the same for the body and try to remove everything from the body and rubber so therent any ridges bumps when remounting.
Use alcohol and wipe down the back of the rubber and body but dont pour it on the body. Pour a little at a time on a rag and wipe down. Dont saturate it.
Slowly use the glue on both body and rubber and start at one corner. Put it in place and hold it with your fingers firmly for 2-3 minutes. Bend back a bit of the rubber so you can keep putting more glue on the rubber and body. Dont use too much so it doesnt drip all over and down into the creases. Small thin consistant layers spread thin! Do this over and over. Apply thin layer of glue, hold in place and again. The end corner will have to tucked in place as the rubber was stretched over time but it will go in place. Just tuck in as the rubber will compress a bit. But ive done it a few times already and it has yet come part on anything i did. Sorry typing from iphone. And all the cameras above, i did the whole body. Came out kick azz!
i will get the door rubber as well and do that and will video it but its some time because i live o erseas.
The hdmi port is my concern now as it hangs out and it annoys my eyes to see it like that
