my 1870-1 is garage kept heated in the winter, I keep my deck clean, the underside get washed to prevent build up and I keep the top side clean, the rust is under the paint on the outside, one spot is on the side of deck in front and the 2nd spot is where the grass deflector gets attached to, I removed my deflector because I bag 98% of the time anyone else have this issue, or do I keep my stuff to clean... the rust locations are around where they weld parts to the deck.....
