The paint on my calmini bumper is showing lots of rust bubbles and has already started to flake off some paint and its only 8 months old. The calmini sliders which are a year old are having some rust isssues away from the scratches. Right side is starting to flake large sections off while the left is about to start as the rust is visible under the paint. I'm planning on having them both sand blasted and will repaint them this summer. ND is a non salting state thank god.
