Baby powda on your seam grip repairs

Just thought I'd share a little tidbit of info I've gleaned from the web about seam-grip repairs.

I have a Sierra Designs Omega 3/4 season tent that is a few years old, used heavily, and after a night of drinking I accidentally stumbled into the vestibule and tore the window off the front.

I had a friend sew it up with beefy line after it was taped with this really tacky tape, then I seam gripped both sides. I thought it'd be done once both sides dried, so I packed it up. When the two sides of the window touched each other from being folded, they stuck together, despite both seam grip sections being dry. So, after fixing these little spots where it pulled and bubbled the seam grip, I applied baby powder to the entire job which completely eliminated the problem.

Just thought I'd share a way to make my favorite repair tool even better and more effective for those of you trying to fix their beloved tents. This would also be helpful for those seam-sealing their seams anywhere on their tent. Maybe this is common knowledge, but it wasn't for me!

Just make sure to use non-starch based baby powder.

Why is that? To eliminate mold ETC?

or is it to avoid having a non-newtonian glop of mess when it rains on your repair?
