Going on the second season with my Clam Portage and am not very impressed with it. I have multiple complaints but my main one is that the fabric has become see through in a couple spots. There are no rips or holes but you are able to see through the fabric when the sun is shinning on it. It is on the side walls of the shelter. Whats is the best way to fix this? Should i by some of the patch material and patch it?
