Hey Dan Im having trouble responding to you on the regular site. They'll only allow me to respond once every 24 hours. Didn't use to work this way. Anyway it just looks sloppy. I hosed it down with a water hose and it didn't leak but that doesn't compare to a sustained rain or snow storm. Fwiw Ive sealed a few tents and tarps like this and theyve never failed. Ive soled a few here and never had any complaints.
