Tub Repair Kit & Porcelain Repair Kit (Color Match) - 3.7 OZ Fiberglass Repair Kit with Super Adhesion, Bathtub Repair Kit for Cracked Bathtub, Perfectly Treat Cracks, Holes, Dents, Worns and Shower

I discovered a long crack almost all the way around a sink that I had purchased second hand. Part of the crack was large wide and sharp and posed a cutting hazard. I was faced with either replacing the whole sink or attempting a repair. I wanted it to look nice because it was going into a newly renovated property. I followed the well-written instructions and it totally worked. The finished results are almost invisible -- it looks and feels almost original. And most-importantly the crack is not longer a hazard. As expected, the application takes several different steps, but I think its doable by almost any adult. I had a sandpaper attachment on a drill with several grits that helped speed up the application, but the crack was exceptionally long. If you just have the more common short crack (like 1/2 inch) or blemish, then totally manual application should be easy and quick. I did the whole application in one session, albeit taking short breaks to wait for things to dry (about 2 hours start to finish with drying times). This kit is not just a band-aid fix. The results are next to flawless, so it truly will save your porcelain appliance. The only thing I can't speak to is longevity because I installed it 2 months ago and have barely used the sink, but based on my observation I think it is as permanent as the rest of the sink.

Worked great. On vertical applications, i would advise letting it setup a while to firm up.

I bought a new shower stall that wouldn’t fit through the door without removing the door frame. It sat outside until I could get help. In the meantime a strong storm blew down some big trees. One branch hit my fiberglass shower stall and punched in the fiberglass a bit. I pushed it almost back into shape and bought this product in hopes of repairing the giant cracks and areas where the resin had broken away. After the first coat, I was super impressed by the coverage and ease of application. I need another box of it to finish, but I feel very optimistic that it will look decent after sanding. This stuff does work! I didn’t fuss with any tinting, as my shower is just plain white and I live alone.Bought another one to finish the repairs to my fiberglass shower stall that had a large crack from a falling tree. The last bit was to the ceiling of the stall. The problem was getting the repair stuff to adhere without dripping from the crack. It did not perform well. I keep having to refill the gap because the stuff is no viscous enough to dry in place. I’ve had to keep refilling the gap where it runs out. Hoping it begins to set so I can get it to dry in place.UPDATE: The maker refunded my purchase price and was gracious to me due to the issues described previously. Therefore, I raised my rating of the product and company by one star. Hopefully they can offer a thickening agent to improve viscosity for overhead repairs. That would put them above the competition.

product is great easy to use and easy to apply has instructions, so it was easy to use.

i used this to repair holes in ceramic tiles. takes a while to dry. kinda sloppy to work with . really sticky when drying so make sure to mix well equal parts and apply to damaged area. seems to do the job. cost effective

Part A of tub is not close to equal to B and both must be equal parts to mix. Need four times amount and thick to cover one sink. And needs something smooth to do corners and each stroke to go into next so it is not smooth. Used fingers in end and does Not come off easily. Used steel wool and witch hazel and scrub to get off hands. And sink used for crazing doesnt look smooth. Will see bit preferred not sand yet as changes adhering. ..need bigger mixing space too and lint from clothes beware. Update within 2 weeks chipping off. Why make such a product? Only to use where not ever touched?? And must be thick to cover cracks but dont say that. Exhausted with games. Beware! Over it . Reimburse everyone plus costs to replace sink, looks like uneven paint job on expensive sink and wont stay on already! Update didn't last two weeks started chipping, all coming off where water touched. Dried for days, took hours to apply carefully ,waste of time. .. Now need to replace sink and no product to fix. Made worse with waste of time and energy ..

To be honest, I didn't use this product for a bath tub repair.I had recently noticed a crack in the inner aspect of the freezer door of our refrigerator and was wondering how I might fix it.Having previously been a dentist I could think of all kinds of materials that I could have once used for this kind of repair, but now I don't really have those readily available and the color match would likely be less than ideal.I decided to try this product and now about 2 or 3 months post-repair, I can say that it has held up well.Having been a dentist I was no stranger to the mixing and handling instructions, even as I got a little chuckle out of the items included to help with the mixing task, itself. They were certainly all functional, but I would have preferred to use my old set ups of mixing slabs and spatulas.Still. the instructions were clear and straightforward and the handling consistency of the mixed product was good, although prone to messiness for those not accustomed to using materials with these kind of flow characteristics.The mix was easy to apply and place.The finishing paper to sand and smooth worked well and I was particularly impressed with the color match.
