It's time to remove the dirty, stained seatcovers from the 240s and wash them up. Looking at ebay, I find all kinds of hog ring pliers, some including rings. Are any of these worth buying, or should I be looking elsewhere for a tool that will do the job for me? And, where can heavier quality hog rings, like those used to hold the 240 seatcovers on, be purchased? Thank you fellow bricksters!
