I need some help I've tried turning it with a wrench and that didn't work, then tried heating it with a flame but that also didn't have much of an effect, also put wd40 on it to try and loosen it up but nothing, if you have any techniques that typically work I'd love to hear them.
Well unless you can find a more local shop, shipping is high due to the stuff the items are put into to keep them safe, so the pistol probably made the shipping go up more. And most safety glasses work, just shoot them with an airsoft gun before actually using them. Its a safe way to be sure they won't shatter into your eye.
Poly sheeting? Poly tank or bucket? Latex glove, tubing, sheet? How strong or durable will it need to be? Simple rubber cement would probably stick two sheets together. If you need something a little stronger, maybe 3M's Scotch-Weld intended for plastics and rubber.
