During the Turbobuick.com Nats event, it was discovered that some (approx 20%) of my new magnetic quarter panel protectors were coming off. Here are the reasons I found. There may be more. Thick undercoating under paint, Bondo on Quarter panel(s), stuck over rubber and mud, large holes in quarter panels, not installed correctly (hanging down off the edge), temp too cold for product to conform to quarter panel, parts cut too long (my fault),. I do my best to provide a quality product. I will admit when I have failed. I've had a set of these on my ten second GN for 15 years with no problems. I've put them on other test cars with no problems. If you own one of the few sets that got sold, you have a very rare Spoolfool product. I doubt any one else will be selling these, anytime soon. I'm sure you can sell them for much more than the thirty bucks you paid. If you decide to run them, just make sure that they are flush on all edges. Many were cut to fit cars without the wheel well trim. If you have wheel well trims, cut 3/8" off the back edge with scissors to not hang over onto the bumper filler. Spoolfool tip of the week: Stick your favorite stickers on your new magnetic quarter panel protectors. Cut around the stickers with a par of scissors and wallah... Instant refrigerator magnets. Big thanks to all who have trusted in me and my products. Mike Barnard Spoolfool Productions.
