I have been using this Simoniz Liquid Diamond for a long time now. No complaints; works as per advertisement. In fact I like it so much that I purchased a bottle for a friend and he too is now hooked on it. I also like the car wash and tire polish. Less

A friend gave me a bottle of it, I used it and was very pleased. I ordered several bottles of the product and was told, after I had not received in quite a while, that the company was out of the product and they could not tell me where I could purchase it. Less

Easy on easy off only been on a month, so far great product Less

Very easy to apply, I polished a 2009 honda minivan in 35 minutes. Polish lasts about 3-4 weeks. Not very long but so what---- Takes longer to wash and dry then to polish! Less

Now I order it through uvip- which is probably far cheaper ultimately. I've stocked up on this since I use it for my wife's car, my car, and my mother-in-law's car. Creates a nice shine and helps protect the finish. I'd recommend this product to anyone. Less

I used this on my very faded Corolla, and it had water beads the next rain! It was so easy to put on that I didn't think it could be working, but it brought shine to a car that hadn't been waxed in years! Less

Ran across this at a big box store, and figured I'd buy it just to get the motorized sprayer (planned on using the sprayer for tire dressing-carpal tunnel donchaknow?). Was so impressed with the wax I went back and bought the few bottles left on the shelf, but I don't know if the sprayer's going to ...work for tire dressing as I had originally planned-may not be enough of a "mist" for that?

Think I've tried `bout every type of spray wax out there and the Simonize works as well if not better than the others I've tried, as well as being as economical (twice the price, but 32oz vs. 16 oz for all the spray waxes I've bought). Some I've tried/have on the shelf:
Black Magic Spray Detailer (one of my favorites, plus a great fragrance)
Meguiar's Ultimate Quick Detailer
Meguiar's Quick Detailer Spray & Wipe
Eagle 1 Nano Wax
Eagle 1 Wipe & Shine
Eagle 1 Wax as U Dry (think Consumer Reports liked this)
Kawasaki Spray Polish (can-good when more cleaning desired)
Kawasaki Wipe Down (can-good when more cleaning desired)

I don't know that one can expect any spray wax to last but so long, but since they're so easy/fast to use, they don't have to.
This stuff beads water extremely well (I also use it on my windows, particularly the windshield) and I often use it for a quick touch-up instead of having to wash a vehicle. I think the spray waxes work better on windshields than Rain X windshield treatments (as well as being easier to apply), and at highway speeds I often don't have to use my wipers.
I've only used this on vehicles with good/new paint (white, silver, dark blue) so I can't tell ya what to expect from older paint jobs. I didn't notice any streaking on my darker vehicle.

Came close to giving it 5 stars, but since there's always room for improvement...
If it lasts longer than others I've tried, I may have to up my rating to 5 stars. Read more Less

I have use Liquid Diamond just one time. The battery opporated sprayer works good, but a regular spray would work just as well... novelty effect I suppose. The liquid goes on a bit runny... like water with a white coloration. It takes quite a lot of product to cover the whole car, but looks really n...ice when done and water beads up during rain nicely. I put some on the windows and it worked very well. Even the windshield wipers worked better.
