Schultz Laboratories Metal Polish with Long Lasting Sealant, 12 fl oz is a Cleaner, Polisher and protectant All in one. Removes Oxidation and Discoloration from Aluminum, Brass, Chrome and More

I don't always write a review, but this product deserves a little of my time. I own a 2019 Audi Q7 which according to Audi has some etching on the aluminum trim cause by the car wash I typically frequent. Apparently, if the car wash facility doesn't mix their chemicals properly it can cause etching on aluminum or other metals. Note: the damage is not covered by Audi's warranty. I have been living the my rather pricey SUV looking less than, well, pricey. I decided to give this product a try and honestly fully believed I would be returning it due to lack of making the trim look better. I was pleasantly surprised when this product worked quite well. It didn't recover the trim 100% but it clearly made a huge difference in the appearance. Up close you can tell where the chemical etching happened, but from short distance you can't tell it was ever damaged. Unfortunately, I did not take "before" photos of the trim. But trust the guy you just met over the internet, THIS PRODUCT WORKS!I highly recommend giving this product a try.

This stuff is great - easy to apply, wipe off and give the piece a quick buffing. I used this on my 2019 Porsche Cayenne's tail pipes and they look great. I picked up the Cayenne in Ann Arbor Michigan, so the tail pipes were looking pretty sad. I hit them with some NeverDull first then followed up with Shultz Laboratories White Diamond Metal Polish & Long Lasting Sealant. Now the tail pipes have a nice warm glow. It was easy to use with very satisfying results. Using the NeverDull took more elbow greae and between the two products I am very pleased.

Removed spots and polished my engine, wheels, tail pipe, etc. in a flash. Wipe on, let sit for a minute and polish off. So quick and easy and does an excellent job!

Works well on brass. Doesn’t leave a residue like Brasso.

Very natural feel.

Only need little bit and it works. Smells nice too!

I’ve purchased my 3rd bottle of this because it WORKS and works GOOD! I use it almost exclusively on my Harley chrome parts. It goes on easy and shines to a brilliant luster with out much rubbing at all - wiping it off is easy but does require flipping the polish rag 2-3 times to remove all the film. There is two things to be wary of. First, it’s pretty runny stuff. Apply carefully to your rag/towel in order to polish the item/area you desire to clean. It does get thicker from a natural evaporation if you have it for a year or two. Secondly - DO NOT get White Diamond on anything dark colored & textured. You will NEVER get it to clean up from any textured metal or plastic.

I’ve used probably 10-12 polishes, primarily for aluminum diamondplate, but none as good as this one. I bought three separate brands before undertaking my current project. One brand was my go to for about 15 years- no more! White Diamond is faster, leaves a higher gloss, and is less work than any other that I’ve tried. Just ordered my second bottle!
