Hi all I have a filterqueen model 31 from a thrift store. It has been sitting for about 3 years and is in decent shape. I just got filter cones and after filters for it. However, some time in its life some water got into the bucket. The rust isn't too bad I was thinking about re painting the inside of the bucket. I was thinking of masking of the filter support and using some red oxide primer because it stops rust really good and them looking for a color similar to correct color. Any advice? I would assume a smooth and clean inside would make it work a little better as dirt collects.
