Works great on my cultured marble tubs and vanity! Super easy to use. Seems to protect it very well from water and soap scum. Will definitely be buying again as it is affordable.

I have used this product for 25 years. If you have any kind of blemish in a paint surface it will take it out. It works great on spots that you might believe will not come out. It works wonders on Gelcoat for fiberglass boats or any fiberglass surface. It brings the brightness back. This is best for spot treating and then use a wax product to seal the surface.

I bought this hoping it will protect a so-called “cultured marble†vanity countertop in a bathroom. I had to essentially restore this countertop because it was severely etched and pitted (apparently by normal bathroom personal products, no hair coloring or hair bleach involved).I don’t see anything wrong with this product, but I can’t tell how well it will be able to protect “cultured†marble (which is actually plastic composite, nothing “cultured†or marble about it).The terms “cultured marble†and “engineered marble†have to be the most fraudulent terms I’ve encountered in building materials. This stuff is just plastic composite material that’s supposed to simulate marble, but really doesn’t, and it apparently gets damaged very easily even by stuff like liquid hand soap. “Cultured†implies that something is natural but just artificially seeded like cultured pearls. That stuff is NOT marble and in no way was it “culturedâ€. It’s outright manufactured just like every other plastic composite. I would strongly recommend against buying any “cultured marble†anything or you’re guaranteed to have problems.But if you have some anyway, I’d strongly suggest trying to protect it from chemical damage somehow because it seems to be extremely vulnerable to very ordinary bathroom products. This seems to be the most recommended product I could find for that.I wish I could say how well this gel gloss product works for protection, but I don’t really want to put blobs of different stuff on the countertop to see what it will protect against. I just figure it must be better than the nothing that was being used before.What I can say is that this stuff will not restore damaged cultured marble. I had to get out fine grained wet sandpaper to remove all the pits, etching, and scratches then use both rubbing compound and lighter abrasive polish, and it was a huge amount of work.But this isn’t supposed to be restorative, just shine the plastic up some and help protect it from damage. At those things it seems to work, I just don’t know how good the protective value is.It doesn’t smell bad and it basically goes on like car wax. It should also come in handy for other plastic surfaces, I’m just not sure which types of plastic it’s good for.

I was looking for something to remove old soap scum from 2 cultured marble showers, and there are few effective products because abrasive cleaners are not recommended. This is labeled as a polish, not a cleaner, but it removed most of the scum spots by scrubbing with a soft cloth, and didn't damage the surface or remove the shine. For the remaining tougher spots, I used Invisible Shield Limescale & Stain Remover, which is safe for cultured marble. Then I went back over it with Gel-Gloss because it contains carnauba wax so it will make future cleanings even easier. I wiped off the waxy haze with a cloth microfiber towel and it all looks shiny and clean.

This is a good product if you only want to shine your cultured marble countertop. But it will do nothing for even the smallest of scratches.

I have been using Gel Gloss for many years. I use in bathrooms on tub shower cleans off soap scum leaving protective coat on. I also use on Camper siding cleaned it nicely and took off white oxidation and bugs. Gel Gloss does a great job on Boats also taking off lake water spots and leaving protective finish.

Bought this to try to bring a shine back to my fiberglass shower/tub--it did NOTHING (no difference). As a matter of fact, the part I didn't use this product on, seems smoother to the touch than the part I used the product (and I buffed with a soft clothe SEVERAL times). I will say it did great on my chrome fixtures. Not impressed for bringing shine back to a shower --- great chrome shiner!

Years ago an old timer told me this was the best product for tire marks on my fiberglass boat. And was a good price. He was right. Still using it 30 years later but now it is fantastic for bathroom sink and tub. Cleans and fill in pores so dirt wipes right off. Love it.

I used this product before but as a spray; which I cannot find anymore... I find the spray works better as you can control the amount being used and you don't need to rub it in as much. However, it does work well and I regularly get compliments on my bathroom and kitchen counters! :)

I have been using this product for years. When we had a motorhome I used it to polish the outside . I now use it for my shower and bath tub . Could not wait for it to arrive a couple days ago.. Its so easy to use and does an amazing job.
