Product Description

Scientific breakthrough that introduces an entirely new dimension of gloss and shine.


DIRECTIONS: SHAKE WELL. For best results, apply to a clean, cool surface. If finish is neglected, pre-clean with Meguiar's Detailing Clay. Apply small amount of product onto applicator or foam buffing pad and spread a thin, even coat onto painted surfaces. DO NOT APPLY TO VINYL, RUBBER OR CLOTH SURFACES. Use overlapping strokes to ensure uniform coverage. Allow product to dry thoroughly (approximately 10-15 minutes). Remove using a Meguiar's M9910 Ultimate Wipe Detailing Cloth, or any other premium quality, clean towel. Turn to a dry portion of towel for final wipe.

TIPS: Use Meguiar's C2000 Detailing Clay prior to application of M21 Synthetic Sealant 2.0 to ensure a Smooth-as-Glass finish. For best results, apply product using Meguiar's DA Polisher and Meguiar's W8006 Soft Buff Foam Polishing Pad or W9006 Soft Buff Finishing Pad. For optimum results when using a rotary buffer, use a speed setting of 1,000-1,400 rpm & light pressure. To ensure product is ready for removal, quickly swipe finger across panel. If surface is clear and streak free, product is ready for removal.

Super easy to work with, applies well with a DA, a little goes a long way, looks great. Leaves behind a solid shine, good beading, and hides minor swirls which my customers appreciate if they are not willing to pay for paint correction

M21 2.0 is old faithful. Like Jon from Forensic Detailing on YouTube said a "stalwart old lady of a paint sealant".

But the reason it's been so well loved for so long, is because it works. M21 2.0 to me is a premium grade, high performance, durable, long lasting paint sealant.

I apply a nice, thin layer with a finishing pad on my PC 7424, and allow to dry until fully flashed before wiping off.

M21 wipes off beautifully, and leaves a super slick, shell-like finish. It imparts a super glossy, rich shine to the paint.

Meguiar's #21 is an "old friend" when it comes to paint protection. I apply it with my Griot's Boss 15 and Griot's 3" polishers and Lake Country CCS finishing pads. To get more protection out of the sealant, top it with Collinite 845... it is like a suit of armor for your vehicle' paint!
