Duct tape is certainly not a permanent fix. It may stop the loss of air temporarily but later on it will fall out when it dries out. People think that hot glue will end up being a permanent fix but the truth is, it will make the condition of your air mattress worse because the hot glue will melt the material and will end up making the hole bigger. So, it is certainly not a fix at all. Never try to seal the holes with a hot glue gun because it will not work. We know its tempting, but don’t!
