What about finding a slow leading edge leak? It takes 60 minutes to lose the pressure and it is still quite flyable. The micro leaks can be from cactus or beach grass
I usually can't hear the leak unless it is large.
Thanks in advance

Pump up the bladder in the kite, spray soap water on the leading edge and you should see bubbles. This method will help isolate the area with the slow leak, take the bladder out and dunk the general area of the bladder in a tub to find the exact spot then patch.

A lot of people here mentions Aquaseal. I guess you mean Aquasure? Aquaseal is for fixing neoprene. Aquasure is Uretane rubber glue, and is excellent for fixing "everything" , though it must dry overnight, if the accelerator Cotol-240 (I think) isnt used.

there is a product used in sailing.
do you think that would work on ripstop fabrics to prevent early damage from salt and sun.
this is what it is about:

I noticed a 1-2 inch area in the canopy by the LE where the stitching frayed. The stitching doesn't seem to be holding a seam together or anything. The canopy is one even piece where the stitching passes over. Is there an easy way to fix this. Could i use Sail tape or could i re-stitch it as the stitching doesn't seam to be holding anything together.

First, I would atleast put some glue on both sides where the seam is still okay, to stop it from expand even further.

still waiting for an answer about the 303 hig tech fabric guard

anyway if you are lookin for a strong glue to repair sails there is also this one used in sailmaking.

its really easy to find in the u.s.

I landboard using C kites and as a result I find the leading edge wears away quickly. Here's a link to a post I did about repairing holes in the leading edge. http://www.racekites.com/forum/forum_posts.asp?TID=20362

Thing is with waterproofing is that tape patches won't stick well when you need to fix the canopy... for do it yourself repair.

Just an update. Here is what I did: opened up the main seam and then taped the tear together with insignia tape on both sides. I was unsure whether this would be enough so I cut a bit of dacron to follow the tear and stuck it on with double sided tape. Then I sewed it, and added a larger patch on the outside to give a better cosmetic finish.
In the end this was probably overkill. Looked OK. Hardest bit was sewing the leading edge back together. That's tough. Had to go over it again in a couple of places. Kite sold.
