A powerfully aggressive cleaner that gently removes serious paint defects.
If you need to tackle major paint problems--the worst possible stains, scratches, blemishes, and serious oxidation--this is the product for you. Developed to power out the neglect, Meguiar’s #4 Heavy-Cut Cleaner is designed to be used with a polisher. Note: Rotary buffers run at very high RPMs and should only be used by someone with rotary experience. Meguiars recommends #4 Heavy-Cut Cleaner be used only with a rotary buffer but you can also use a dual action polisher for excellent results.
#4 Heavy-Cut Cleaner is not for anything less than the worst stains, scratches, blemishes, and serious oxidation. #4 Heavy-Cut Cleaner has enough smoothing abrasives to repair such damage and restore the finish to a like-new luster. Although this is a very powerful cleaner, if used as directed, it is not harsh on anything but the problem.
Blemishes--banished! Many detailing professionals and automobile restorers turn to Meguiar’s #4 Heavy-Cut Cleaner. It’s been a trusted and preferred product for years. If you need to pull out all the stops to eradicate serious defects (not just cover them up) and your not afraid to apply a little bit of elbow grease, you’ll find Meguiar’s #4 Heavy-Cut Cleaner will work wonders.
Definitely works to remove clearcoat scratches. I used a Porter Cable set to 5 and an orange Lake Country foam CCS pad. Took out the scratches without paint damage. Followed up with XMT #3, then XMT #1. Reason for 3 stars: 1. Very difficult to clean out of your foam pad. Greasy residue is immune to dish liquid or XMT pad cleaner. Had to basically squeeze the gummy residue out and then clean and reclean my pads. A lot of time taken to get a rfresh clean pad 2. Too runny and does not stay on the pad surface. Slings off and soaks in.
