Star Nails Fibreglass Resin - 14g - ST875

I just use fibreglass resin to repair my own nails as I play fingerstyle guitar. So i don't use very much, and it seems to go off after about a year - it stops setting properly. So I throw most of it away. I've always had to buy 1 oz (28 gm) bottles, so when I came across this 1/2 oz (14 gm) bottle at an appropriately lower cost, I was happy to go for it. I've used Star Nails fibreglass resin before, and it worked fine. However, the 1/2 oz bottle I bought from Consumer Retail Ltd didn't work properly - it was just like it was old and had gone off. I would buy Star Nails fibreglass resin again, but not from Consumer Retail Ltd. The poor review is for them, not Star Nails.

Good, strong glue that I have seen them use in the salon, however the nozzle glued itself on and the glue is no longer usable, despite there being around half left, I cannot get it out of the bottle
