X-Chef Tub Repair Kit Color Match, Fiberglass Tub Repair Kit for Cracks and Holes Repair on Acrylic and Porcelain Surface, Shower Repair Kit for Tile, Sink Repair

For the size of repair I did - which was a very small are on a cultured marble sink - it did fine. I originally did not think that the colors provided would be conducive to a good color match, but I was actually able to match the very soft beige color very easily – just follow the instructions and use only the tiniest amount of tint and add more of the white two-part mixture if your initial try is too dark.My only real suggestion is that the manufacture include a flat-edged tool in the package – while the curved spreader is useful for getting the mixture out of the color mixing tray to apply it, it makes it difficult to spread the product on a totally flat surface, and would be even less useful for a convex surface such as the edge of a tub.

I went in with low expectations after reading reviews of other, much higher priced similar items. Very glad I chose THIS product. I actually used it to repair a tub that had an area the size of a dime in cracked/chipped fiberglass. It covered up the dark colored portion of the hole, and blended in so well you can't tell where the repaired area is. I also used it to fill a hair-lined crack, which naturally was easier to repair. There is a learning curve, however. If you add color to the white paste, VERY little goes a LONG way.

Had a bad Crack in my tub, bought this, followed directions and now you really can't see it at all. Was able to match color great.

Good stuff. Durable, mix in color matched great. Don't apply more than you need, it is harder to sand it off than you might think.

Easy to use. My sink is white so i didn't have to mix color.

I got these for a fiberglass bathroom repair. on a large Y shaped crack. After I got everything lined up on the crack I went to work with the product could not see the damage and it held when I pushed against it.

At first it seemed pretty good. It wasn't too hard to mix the colors to get it perfect and it applies easy. Fast forward a few days and it has started to separate itself from the tub.
