Success! I couldn’t tell if it was discardable. I hammered a screw into it (‍♂️) and [pried it right out](https://i.sstatic.net/luuww.jpg). Thanks, your mastery of cans is impressive indeed.

<p>Ok. I have this can of Castin’ Craft brand polyester resin that is brand new. I unscrewed the top and was confronted with a second metal barrier:</p>

<p><a href="https://i.sstatic.net/u0Ph7.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/u0Ph7m.jpg" alt="enter image description here"></a></p>

<p>I’ve tried:</p>

<ul>
<li>Prying it with a screwdriver.</li>
<li>Grabbing the edge and unscrewing.</li>
<li>Putting pressure from the inside and unscrewing.</li>
<li>Stabbing it.</li>
<li>Focusing my chakra, prana, and kundalini energy to visualize and create a portal through which I can pour out the contents.</li>
<li>Yelling at it.</li>
</ul>

<p>Before I just take a step bit to the top of this can, does anybody who’s used this resin know how to open this?</p>

<p>I know this might be a silly question but I’ve never had so much trouble opening a can before, and believe me I’ve opened a lot of cans.</p>

Ok. I have this can of Castin’ Craft brand polyester resin that is brand new. I unscrewed the top and was confronted with a second metal barrier:

[![enter image description here](https://i.sstatic.net/u0Ph7m.jpg)](https://i.sstatic.net/u0Ph7.jpg)

I’ve tried:

* Prying it with a screwdriver.
* Grabbing the edge and unscrewing.
* Putting pressure from the inside and unscrewing.
* Stabbing it.
* Focusing my chakra, prana, and kundalini energy to visualize and create a portal through which I can pour out the contents.
* Yelling at it.

Before I just take a step bit to the top of this can, does anybody who’s used this resin know how to open this?

I know this might be a silly question but I’ve never had so much trouble opening a can before, and believe me I’ve opened a lot of cans.

Prying with a narrow screwdriver is a good start. It appears in the photo that you have a bit of a start at the near edge of the top.

This particular seal is a throw-away and you can indeed stab it. Something stronger than a pointed stick should do well enough. A small blade philips screwdriver tapped in then bent outward will distort the top sufficiently to pop it free.
