Epoxy holes in small pieces of wood: ziploc bag?

I'm making small wood bookends from a live-edge slab. Some of them have voids and cracks that I'd like to fill with epoxy. My past experience tells me that it will be challenging to create a sufficiently watertight tape job around the sides and bottom of these pieces to prevent epoxy leak, and I am considering other options.

Has anyone tried using a shrink wrap or ziplock bag sealed around the wood piece with a heat gun before pouring epoxy? I could easily do multiple pours if the first doesn't do the job.

Any other ideas for flooding a small piece of wood with epoxy?

(Edit: I'd like to avoid placing the whole piece in an epoxy-filled container due to epoxy waste ($$$) and extra work of getting the hardened epoxy off)

If it is small cracks you want to fill, there are syringes made to fill with glue and feed into the cracks. Or maybe I don t understand the question.

I have no problem filling the cracks, but in the past I've come back in the morning to puddles of epoxy that slowly leaked out of the tiniest holes under my tape. The live edge is the problem, it's very difficult to fully seal it even with aluminum tape.

are you talking about a rough sawn surface,i plane and sand first then seal with tape and fill,no issues.

Maybe just my limited experience, but when I've done a flood coat I got small leaks around the live edge, even after stripping the bark, sanding, and taping the s*&^ out of it.

I am working with a cookie slab, if you can picture what I mean
