Need Advice — Repairing Holes in the Composite Bed

UPDATE: I have probably over-thought this, but after getting over the trauma of putting holes in may wife's truck, I wanted to make sure I plugged the holes, ensured the holes did not weaken the bed or lead to any cracking, and make a seamless repair.

I appreciate all of the suggestions to date, and decided to try an epoxy. My first thought was regular JB Weld, which I happen to have, even thought it dries grey, not black. Then I thought I would go to the local big-box hardware store and ask for product advice. As I feared, this was a huge waste of time. The people who work there know less about materials and products than me, which is a sad commentary, as that's a pretty low bar.

Then I decided to look online at what the bed is made of, and use that information to see what people use to repair this kind of material. I knew the bed was some kind of plastic composite, but learned that more specifically it is a fiber-reinforced sheet-molded composite, or SMC. (This is probably fairly well-known among Tacomaworld, so forgive me if my knowledge seems rather basic.) While it's not made from 11 herbs and spices, the manufacturing process is pretty cool. Using my new-found knowledge to evaluate repair materials, I soon realized that most are commercial products for making larger and more structural repairs to modern Corvettes, jet skis, and the like, with the quantity of material and their cost reflecting that.

For my much smaller and hopefully non-structural repair, I found what I think will work:

$8 J-B Weld 50139 Plastic Bonder Body Panel Adhesive and Gap Filler Syringe - Black - 25 ml

J-B Weld 50139 Plastic Bonder Body Panel Adhesive and Gap Filler Syringe - Black - 25 ml -- $5.96.

It's advertised as both an adhesive and a gap filler, is supposedly suitable for repairing SMC, and the label says it dries black. I'm going to give it a try and will let you know how it went -- unless someone here shouts out: "Don't use THAT!" LOL.

How did the JB weld work out? I just did the same shit to my wife’s 2022 Tundra and 5 holes on each side of the bed. Found out too late.

I'd use Lord Fuzor 101EZ. I've had more failures than successes with J-B Weld.
