    Unhappy How to repair scratches and gouges on hard bags?

    I could really use some advice on how to repair minor damage (as in tip over) scratches and gouges to BMW hard bags? Mine went over at a standstill while making a uphill right hand turn into a driveway, and not paying enough attention. Boy, does that happen fast. The wheel cocks, and it just starts to go. No stopping it. I feel bad, I love this bike. Is the black color all the way through the bags? That would be helpful so that I didn't unintentionally make the damage worse by sanding through a surface coat and end up with some grey color splotches. I was thinking of trying to so some fine filing/ sanding on the bags then try to airbrush a flat or semi-gloss black paint onto the repair. Does that sound like it would work? What have others done for this situation? Is there a special paint, or spray that will help here? Thanks, everyone.

    I have used auto body spotting putty and rubber bumper paint to fill deep scratches. Spotting putty and truck bed liner also works very well. I've used both.

    I had mine come off at about 70 mph and they got a bit scuffed up.
    My self esteem took a much bigger hit, as it was because I had left both of them unlocked! At least they were empty.
    Anyway, I used 150 and 220 grit sandpaper and a random orbit sander to take out the scratches/gouges. Then some Scotch-brite to finish it off.
    Surprisingly good results. With an application of Vinylex, it's hardly noticeable.

    right along with this thread, what can I use to clean my side cases?

    They got some stains of some sort on them and it looks oily.

    saddlebags et al

    I had a 94 with the saddlebags matching the "Pimp White" (aka pearl silver) body color. One of the bags got scratched up and when I spoke to my friend who owns a body shop he told me that the cost of the paint was astronomical. After thinking it over I decided to snoop in an auto parts store where I came upon a display with rubberized white/grey/black spackle (sp?) trunk paint. Took the lids off and sanded them up enough to rough up the surface then shot both lids with the stuff. I was surprised at the number of compliments I received as well as how good they looked. Additionally if I scratched one of them all I had to do was wash and dry the surface and grab the can of paint to fill up the scratch. Might be worth a try.

    As for cleaning, carwash soap works well assuming there is no oil on them.

    Paul mentioned truck bed liner. This is quite a testament to the Line-X brand. I'm not affiliated with any products.

    I have fixed more than one bag with nasty scratches. I start with about 220 grit wet dry sand paper and work my way up to 1500 to 2000 grit using lots of water and clean sand paper.. I then coat it with Pig Snot, they look almost new. Just did it again on the bags on a new to me R1200R that came with scratchs on both bags from a number of get offs. They came out great.
