do you have to apply on both sides of the seam or just one side? also if it's one side, is it the inside or outside? thanks!

Hello, Thank you for the question. For the best seal I would recommend applying to both sides. Apply one side allow it to dry and then apply the opposite side. Please let us know if we can further help in any way. Thank you, Justin J. HouseofScuba

How many tubes would be needed to seal a 2-person sil nylon tarp? It has a ridge seam and two "gable end" seams.

One tube should do the job, unless you really goop it on thick and heavy. I have been working on a rainfly for a 4-person tent. It has many seams so I had to get a second tube. A two-person, simple tarp should pose no problems to cover with a single tube, IMHO.

Will this work on an older tent to seal the seams?

Hello Buzz, This sealant is designed to seal up seams coated in silicone which occurs on most tents. I would double check that your tent has silicone treated seams but it most likely would work without any issues. Please let us know if we can further help in any way. Thank you, Joe P. HouseofScuba

Can I use this to adhere screen mesh to patch a 4 inch hole in the mesh portion of a lightweight tent?

I think it would work fine. Down side is that there is not as much surface area for the adhesive to bond to. I personally would hand stitch the patch to the screen and then go over the stitching and the overlapping portion (border) of the patch with the Seam Grip.
