The package says there is a cloth/swab with it, but that was missing. Two cotton buds are not enough. Plus, a cotton bud is too wide to go into most of the areas that need cleaning (the top and bottom rails seals of the back door). When you look at the package content, the actual foam seal is just one piece with no visible markings to reveal that it has actually been partly cut for the camera. Only by bending the foam does it reveal where each small "gap" is. When you try and remove a single piece of foam it is still partly stuck to the foam next to it, and breaks as you try and use the tweezers to remove it from the paper backing. This is because each piece of foam is so thin. When you finally succeed to get one long piece lifted, it is then stuck to whatever you lifted it with (so best to dip that in water beforehand). It is almost impossible to get the long door seals to lie into the grooves flat. You can't tease them into the clean gap without the sticky side grabbing against the side rail on the way in. Even covered with ample water to make them temporarily less sticky doesn't entirely fix this issue. I have completed the job, but the camera door now "sticks" to the seals slightly as you open it, and you can't avoid having some of the white sticky side of the seals visible - so cosmetically not ideal. I do not recommend

Habe die Dichtung zum ersten mal selber ausgetauscht, und mir sind ein paar Streifen gebrochen. Das ist wahrscheinlich mein Verschulden. Jedoch waren mehrere Streifen nicht komplett geschnitten (Klebestreifen), somit war es sehr schwierig einige Streifen raus zu ziehen.
