Fiberglass Tub Repair Kit (Color Match), 3.7oz Fiberglass Shower, Porcelain Sink and Acrylic Bathtub Repair Kit, Quick to Fix Cracks, Chips, Dents, Holes on Bath Tub & Toilet, Almond/Biscuit/Bone

Works great, easy to mix, very strong when it's dry

I was fixing up a rental in which the tub was cracked. This was the perfect affordable solution to our problem rather than replacing the shower/tub or having professionals come in and do it. The professionals wanted $300-$700 to fix the problem. I didn't have to mix the colors, just used the white. When I tried to sand it, the epoxy took on the gray color of the sandpaper, so I let it be. Overall, I would recommend this product for price, ease and effectiveness.

I'm very happy with this product's performance and ease of use, but in order to get a color match for my old 1970's almond tub, I had to purchase this kit, which includes yellow, in addition to the HomeTinker kit, which includes a pinkish brown. I mixed a little yellow and pinkish brown, and got an excellent match for the pale yellowish almond color of my tub. So my only complaint for this product, and also for the Home Tinker product, is that it would be nice if they included both the yellow and the pinkish brown, along with the included black. Even with having to buy two different kits to get the color I needed, I'm just glad there is such a product, that does such a great job without noxious fumes! It's wonderful! And here's a great tip for smoothing it! I have a little rubber or silicone squeegee from a Skinomi screen protector kit, and it was perfect because it's flexible. It worked much better than the hard plastic putty knife, and allowed me to smooth rounded edges and corners. It came out great! Of course, there's still some sanding, but not as much.

Works ok but not great. Patched the crack but a new crack then appeared in this product. The color seemed to cahnge over time as well.

I ordered this product to fill some holes in my shower tiles, The first order I received had the bonding bottles overflowing and I could not get them open, So I returned it for a replacement, thinking I could do this and that it looked to be a fast fix. However when I received the seconds package, it looked similar to the first one I received having overflows in the bonding bottles but not so much that I could not open them, I started step by step and laid everything out. When I tried to mix the two bottles Part A and Par B Together I noticed that in the stepped pictures they were using a spoon in step 1 and 2 rather than the enclosed tool to combine them so I got a spoon and mixed the two parts together. Also when I started to mix the color agents the little plastic jars were very tiny and also in the mixing step 2 they show using a small spoon to take out the color agents , not to be deterred I got out my tiny spoons and began to transfer the color agent over into the mixed bonding agents. There was no way I could derive a light grey color as there were not enough orange color mix to get anything but a lighter black color. At that point I had to give it up as putting black putty on my grey bathroom tiles wasn't going to work, so I threw in the towel. Perhaps this could work on a white surface or something darker. Beware you may not have all the tools to get the colors out of their containers and that you might have difficulty mixing Part A and Part B without a spoon and It's very messy and pair of plastic gloves enclosed will likely not make it through the process as mine tore up just getting the lids off Part A and Part B

After I got a new house and find that shower tub has a huge crack, but too late since it was sale as-is, and I didn’t catch that. I was told to just replace the tub, which cost about $200-300 minimum and additional labor cost. I find this product and give a try. It works well. Little patience and art work skill (I’m horrible at both). The instructions are easy to follow. Recommend use tape to tape around the work area for less clean up work (not instruction) depends on the area you work with. It can take up to 24 hours to dry, then sand off to smooth out. The sand papers provided will not be enough unless you are really good at the art work that already think and smooth. I bought some extra high grits and low grits sandpapers to sand off excess and smooth the work area. Little difference in color, if you want perfection, buy the pain for tub. Perfect DIY fix and save big bucks.

Used this to fill a crack in my hot tub. Getting the color to match was harder to do than expected, resulting in some waste. Other than that it is fairly easy to use. If you follow the online tutorial your fix will turn out great. I had a large crack that needed some additional buffing to blend, but is not noticeable except for the slight color difference. You would have to know where to look to find the repair. My only additions to the product would be a warning for an inexperienced user to drill a small hole at the end(s) of a crack to help prevent it from cracking further, and a finer grit sand paper added to the kit. I used a 3000 grit to finish sanding before a final buff.
