Hello everyone... We created dual stage foams from stock foams. We hand painted the inner part of the stock foams with 2 to 3 coats of acrylic paint. After putting the foams in tires we noticed some of the paint cracked so we had limited success. Check out are YouTube video for more details. Please leave a comment if you have any solutions. Also check out our channel we are in the process of building some sweet backyard trails.
