You don't need a kit, there aren't any fancy seals in the A35F. I did mine just like I do all of my cameras. If you go to your local craft store you can find two kinds of black felt. One has an adhesive back and one doesn't. Your total cost should be around $2. Put the adhesive backed stuff on the flat parts of the door and cut the non adhesive felt into thin strips for the other gaps. Even if you've never done it before, you'll be done in about 15 mins. Its very easy.
