PNWGUSMight want to reach out to UGQ directly... they offer it for something like 12.95 on their site. Not sure if it is possible... it's also not terribly complicated. Several videos out there, I do believe they even have one on their site.
PNWGUSFirst thank you for joining the drop, it's a GREAT price on a GREAT tarp. Due to the high number of tarps we do not have the dedicated spaced needed to offer seam sealing on these drops. We do have a video on our website showing how to seam seal your new tarp and as mentioned it is super easy DIY project.
