TR Industries Gel-Gloss RV GG-16 Polish and Protector 16 oz.

The water supply to my home is damaging cultured marble bathroom surfaces. Perhaps it is acidic. The Gel Gloss seems to provide an effective wax which keeps the water from direct contact with the surfaces. It also makes the surfaces shine again. I wish I had used it sooner.

USE ON OUR FIBERGLASS POOL AND SPA. WORKS REAL GOOD

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 “cultured”. 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.

This really shines up a shower after cleaning it. Shines “ like the top of the Chrysler building”.

What's so great about a product that does nothing but polish? Don't waste your money if you're looking to get rid of sun stains on cultured marble. I thought I was getting something for $20, so I'm disappointed.

I use this on cultured marble countertops in my bathrooms. It works great, easy to use and leaves a great shine.

Works great. I bought it to restore the original shine on my center hubcaps. I needed to re apply several times due to how dirty the hubcaps were. But at the end the hubcaps regained their shine.

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!
