Any owners of SKS fenders, can you tell me if they are paintable? I have tried calling Harris cyclery several times for the past few days and biz must be so great they don't answer the phone, I get the "high volume of internet traffic....." message. I want to buy from Harris because there are a few other items I need as well and can combine and save shipping cost. The fenders I am looking at are the black ones and they are described as having a gummy (what does that mean?) finish. Is it like an automotive finish like a plastic bumper? I want to scuff it up, spray bulldog paint adhesive/color/clear. I asked a similar question last week, but it was about Planet bike fenders. If SKS are a no paint then I will get the SS Berthoudz.
