Hey DD, were you seam sealing with seam grip or spraying a waterproofer over the fly? If so, what did you use? I have a 15 year old Mtn Hardware tent that in several spots is starting to mist right through the fly (not the seams) in a hard rain. Moonman.

I was putting on a waterproof spray on the fly of an older REI tent that would weep just a bit (less than a teaspoon) in a hard rain.  I used Camp Dry spray on one end.  The end I sprayed did just fine.  Unfortunately, I sprayed the WRONG END!   :-[  Now I have to let the tent dry before I spray the OTHER end.

If that doesn't work, I'll make my own ... I already have the clear silicone and mineral spirits to make my own solution.  I may try a pump bottle application.
