Odd, like we're talking about two different products here. Half the people, including me, have had no problems with Platinum. I shoot about 100 arrows every morning, both carbon and aluminum. Really take no special pains when fletching them. Have to pull the occasional arrow through the target when it finds a weak spot. Have had no fletches fall off with Platinum - none.
Others, who I believe are also telling it like it is, can't get the stuff to stick. Wonder what's going on?
Okay, this is the way I fletch arrows: I put the feather in the clamp, put a line of glue all the way down the quill, and then press it onto the shaft, which is in the fletching jig. Let it sit 15 minutes, and then rotate to the next feather. I usually fletch in my kitchen where the temperature is about 65 - 80 degrees, depending on the time of year. I feel stupid saying this, since this is probably how everyone else fletches arrows too, right? But there must be some difference somewhere.
