What do you guys (with no leak tanks) use to scuff up your skins and ribs for Prosealing. I've used Scotchbrite and a plastic wire wheel, but I've heard I should be much more severe and use #40 sand paper and really scruff them up so the Proseal will stick and never leak. So what did you use and how deep did you make your scratches. Thanks
