GoodfillaNeutral tintable Base, 12 oz, Wood and Grain Filler Powder, Stainable, Paintable, Sandable, Versatile | Zero Waste

I was not expecting this wood filler to have a pleasant smell, slightly sweet and minty, but it does, and that’s a nice bonus. It mixes easily, works just fine with water, dries pretty fast, seems pretty stable. I’m mostly using it under veneer, in deep gouges, and to fill hardware holes, so I won’t comment on stain-ability or how shellac looks over it. Walnut matches old Singer sewing machine cabinets pretty well.I would suggest grabbing a cheap set of measuring spoons to dedicate to wood filler, and if you don’t already have a digital scale and disposable cups in your shop, you might want to add those to this order. You don’t need anything fancy, just accurate.As for clean up, it wipes off of tools while wet, and if it dries on the tool, you can either flake it off or wash it off the same or the next day.The best part? You mix what you need, you aren’t stuck with a tube that’s going to be dried out the next time you need it.

So, I mixed this into a thick pancake batter consistency and worked the rosewood colored filler into the grain of a swamp ash body for a guitar, with my gloved hands. You don't have to be too careful about scraping it, although I did use a plastic card to squeegee some of it off, because it dries into an easily sanded consistency after it dries. I imagine a harder mixture like epoxy would be a different story. It worked well and looked good. You have to be careful when applying finishes over it because it isn't super hard, so I put I a few gentle coats of shellac over it after I sanded it off the flat areas to lock it in. It has a pleasant odor and is easy to work with. It is my first time using grain/pore filler, but I found it worked well for me. I will also add that the fact it is in a resealable pouch in powder form means it won't dry out and go bad, and can probably be used again years later. A defininte plus.

I found this very easy to use and it worked great. The smell was not offending like many other grain fillers. It actually smelled a lot like Petually oil. My only issue with this, and why I didn't give it a 5 star rating, was because the color was not what was advertised. Instead of it being a dark cherry red, or similar to the color strip on the bag, it was more of a chocolate brown color. Which was a little disappointing since I used it to fill the grain on a Les Paul that is going to have a cherry red back. It still worked out good since the wood was mahogany and it matched up very good with it. But I was hoping for a dark cherry red grain. I would still buy it again if needed and wouldn't hesitate to recommend it to someone.

Very sensible to have a dry mix you only make up what is needed. Rather then a jar of premix that turn to cement by time you need again. And has this delightful aromatic smell, like a kind of minty , medicinal. Better than some nasty epoxy smell. Try it you’ll like it.

I got this guitar body for my diy guitar project shown in the image attached to this photo. The filler is easy to use, but messy. It covered most of my deep grain in this guitar body, especially for being swamp ash wood, which has deep and hard to fill grain. This stuff rocks. All I did was add water and let it dry overnight. I highly recommend this to anyone working on a guitar and staining it.

First time I have used this product. Mixes easily, spreads and fills well, does not shrink much, dried overnight and sands well. Unusual smell but not offensive. This will now be my go to product.

This is the fourth different product I've used to fill grain. I liked this product 3rd best, and I would not buy it again. I found it hard to mix, wasteful to use, and a general pain to work with. Read on if you're interested.I've done three bathroom vanities and a set of laundry room cabinets of honey oak with a deep grain. Filla-in-a-bag: Don't follow the mixing instructions, they will leave you will a clumpy unworkable blob akin to stiff cookie dough from the fridge. I had to add 50% to 100% more water than instructed to get something that was spreadable. I found that a consistency closer to thin mayonnaise or even thick paint was needed before it would spread well. Bad instructions and difficulty in getting the mixture the right viscosity is my biggest complaint. It caused wasted product. AquaCoat and SherwinWilliams Shrink-free spackling are the right consistency out of the jar.I could not get it to push into the grain and scrape off the top, leaving only the filled grain. Easy with AquaCoat and SherwinWilliams Shrink-Free spackling, but I found Filla-in-a-bag created an extra layer of material that had to be sanded off in the end. See images. This caused unnecessary product usage.It dried fast, but this became a problem where it didn't stick smoothly. If I went over it again, it clumped, pulling the just applied (5 minutes) layer off unevenly.Mixing and cleaning was a hassle when compared to the other products.I used *more* of this product than the others, because of the mixing coating problems mentioned.The fourth filler I've tried is plain old drywall compound. Messy. Sloppy. Lots of extra material, but dirt cheap. Sands easy. Pretty effective.Next time I will use AquaCoat (easiest to use, best results, least product waste), or Sherwin-Williams Shrink-free spackling (available at local stores, good results, little waste, not hard to use), drywall compound (cheap cheap cheap, easy to sand, and readily available), with last choice Filla-in-a-bag (no cost advantage, hard to mix right, hard to apply well, and product waste.)
