Excerpt: In our Meguiar's Gold Class Showdown, we tested this 64-ounce bottle against both foam and bucket methods, and the results were impressive. The suds formed effortlessly in our foam cannon, generating a plush, lather-heavy wash that gently lifted brake dust without scratching. For the bucket wash, we dipped our mitt into the solution, and the paint felt ultra-glossy, freed from grime. The product proved safe for all surfaces—we even tried it on our lowest-clear-coat vehicle, and it removed residue without damage. The 64-ounce size was perfect for both solo and multiple-car washes. While we preferred the foam cannon’s efficiency, the bucket wash yielded equally pristine results. Ultimately, Meguiar's Gold Class delivered on its promise: a clean, brilliant finish that proved versatile and durable.
