- STARBOND Black Medium-Thick CA Glue Pro Kit (2 oz) – Rubber-Toughened, Impact-Resistant Cyanoacrylate Super Glue – for Durable Knot Filling, Crack Repair, Woodworking, Guitar, Hobby & RC Projects

I use this glue for just about everything and it has yet to disappoint me! Repaired crack on John Deere X530 hood. This has held up for an entire season of mowing. Crack was in the middle of the top. Stress point every time you open hood and I open before every use to check oil. Used to fill chip in guitar finish. Used to glue broken hinge on reading glasses. Will no longer fold shut but works well for spare set on desk. Latest use was a repair to a lawnmower tire sidewall gouge that had no penetration to inside yet was slow leak. Yet to determine longevity of this repair. I used the Starbond aerosol activator on all these repairs. The best part is I've had this 2 oz. bottle for nearly FIVE years! Secret is to seal bottle tightly and keep in freezer door (glue only not activator). Will upload photos later. Note: It only takes a quick spray of activator!

Worth it. If you ever used it, speaks for itself. Try it!

Great stuff, good price, holds well and fills cracks easier

I’ve been using this Starbond black medium thick CA glue for filling little voids and hairline cracks in my black-dyed plywood projects, and honestly it’s kind of a cheat code. I’ll sand the surface, drip this stuff into the tiny gaps, hit it with activator, then sand flush again – the black glue just disappears into the grain and makes everything look way more “pro” than it probaby deserves. Viscosity is right in that sweet spot for this: thick enough that it doesn’t run all over the place, but still thin enough to wick into fine cracks and ply edges. The black color is the magic here – with clear CA you always see that weird shiny line in certain lighting, but this blends in with ebony stain, matte black paint, and even charred/shou sugi ban edges really nicely. It’s not perfect though. The fumes are no joke, especially if you’re using accelerator, so definitely don’t hover over it like I keep forgetting not to do. It also cures very hard and a bit brittle, so I wouldn’t use it as the main structural glue on anything that flexes alot – I still rely on wood glue or epoxy for that and treat this more as a cosmetic and spot-repair fix. The tip can clog if you’re not diligent, but that’s pretty standard CA behavior; I just keep a pin nearby and try not to gorilla-squeeze the bottle. Overall, if you do black furniture, speaker boxes, cosplay props, 3D prints you paint black, or any kind of dark-themed builds, this is one of those “why didn’t I buy this sooner” products. It saves projects that would otherwise look janky up close and makes your finish work look way more intentional for very little effort.

LONG STORY SHORT: I began working in my buddy's wood shop about a year ago, which is when I first discovered CA glue. It's awesome. Just fill in the holes or gaps with whichever one of the glue "thicknesses" works best, and then spray the glue with the Accelerator. The CA glue is dry within seconds. Give it a minute or so, and you can sand it to match the rest of the wood piece. I bought the Clear CA glue kit (with accelerator) separately, but needed this BLACK CA glue to fill in knots and holes that were....well....black. Using the right color makes the glue almost disappear into the wood. With this glue (if you don't already have it) you will need an Accelerator spray to make it dry super quickly. And when I say quickly, I mean, you should be able to sand it within 2 mins or so of application. It's awesome. Highly recommend CA glue in general, and this Starbond Black Medium Thick is no exception. 10/10

Really good glue for repairing weather stripping on most any machine that needs something held together with a super glue that is black and really strong

This CA glue is fantastic for fixing minor defects or instability in your work piece. The applicator is easy to use and comes with multiple tips including ones for precision applying. The color is a dark black which works well with your darker woods and looks nice as a contrast with your lighter woods. Dries very quickly once the accelerator is applied and excess sands off easily. Overall a fantastic product.

This is the best black epoxy filler out there. Sands smooth and easily repairs bubble holes left from epoxy pours.

Seemed a tad expensive but worth it for the extras in the kit

I really liked the short fine tips supplied. used to fill blemishes and highlight in an an Iron bark burl in a wood turned bowl. Thank you

It's glue... dries fast... good fir unwilling imperfections in wood

It appears to have glued these pieces of mother of pearl into this ebony fretboard perfectly. Time will tell how well it has worked.

The liquid is very thin allowing it to drip nicely into cracks and voids in the wood perfectly.
