Meguiar's G19216 Ultimate Polish (16 oz) is a popular product for car detailing, primarily used as a pre-wax cleaner and polish. Here's a pros and cons breakdown:

Pros:

One of the key highlights of this polish is its ability to enhance the vehicle’s paintwork, leaving a glossy, wet-look shine.
Easy to Use:
The product is relatively easy to apply by hand or machine. It spreads smoothly, reducing the effort needed to achieve a great finish.

It works very good & I would buy it again

Actually took this product back to the local Walmart not because of anything that Walmart did but simply because the product itself come to find out will stain plastic trim on your car and I did not want to deal with that. It did not tell that in the description and I found that out after I ordered it from other sites

It works well to finish the last step. Not magic, not wonderful.

I used this with a Harbor Freight Dual Action 6" polisher & pads (Lake Country 5.5 backing plate). With the blue polishing pad it has completely restored amazing shine & luster to my 15 year old oxidized Earl Scheib 1-stage enamel paint job. Darkens/richens the paint color by leaving polishing oils behind (conditions paint too). The only thing that could make this product better was if it could magically remove dents too. lol

Good polish. Easy to use. Good results.

Used it on a car that is 15 years old which had never been polished but car was already in good shape. Applied the polish using a polisher which made the car much shiner and probably closer to what the car looked like new, I think it went from good to great. Would recommend to anyone.

did a great job removing fine scratches, always READ THE INSTRUCTIONS

This polish worked well for my clean car before applying Zymol wax. It was easier to use than the Meguiar's Deep Crystal System polish I used before, but it does not smell quite so good as Zymol HD Clense.

Applied with a DA orbital buffer after wash and claying. It removed all the fine scratches left behing from the Auto car wash. Also used Meguiar s Ultimate Liquid Wax for protection.
