Well, our old tent finally bit the dust after some high winds and pretty good rainstorm. I am in the market for a new tent, and was wondering what folks use to seal the seams on their tents? (We did not on our last one, and I would like to be a bit more preventative with our new tent) Not sure if there is a good brand that does the job well? Also, if you seal the seams, is it done once per year? Thanks.
