gkflying said...The valve on one of the struts has come away from the bladder what is the best glue to seal it up with

Cut circle that just fits over the valve in a sheet of Tear Aid or the Cabrinha patches,

www.kitepower.com.au/catalog/product_16990_Cabrinha_Bladder_Repair_Patches_cat_325.htmlclean around area the patch will cover with metho/alchohol, apply patch.
This fixes a lot of the valves coming off issues, if not put seam stick or this glue
www.kitepower.com.au/catalog/product_16990_Cabrinha_Bladder_Repair_Patches_cat_325.htmlThe glue is available on its own, its $29 for a tube.
Or buy a stick on "U-stick" valve.
www.kitepower.com.au/catalog/product_17053_UStick_Bladder_Valves_cat_325.htmlVery rare to have to buy a new bladder these days with the availability of new products like the above.
If in doubt call one of the crew at Kitepower, we can fix almost any bladder.
