I havent done stock repairs with it, but I would use locktite 420.I have used it on recurve bows with great results.Its best to use a hyperdermic needle to get it where you want it though.The good thing is the stuff runs like water.The bad thing is its about $22 an ounce and you usually have to order it.You cannot "fill" with it and have to have a way of squeezing together yer crack before applying,so yer ready when you do apply.It dries fast and is very,very strong stuff.Some of the exp. builders here may have better solutions though.Good luck.ridjrunr
