Description

The FM-43 Mighty Marker® Auto Body Panel & Glass Marker is a water-based, ammonia-removable wet erase paint marker built for showroom glass and painted body panels. Marks go on bright and wipe off clean with Windex® or any ammonia-based glass cleaner (2%+ ammonia), no scraping or residue left behind. The pigmented, water-based formula is quick-drying, xylene-free, acid-free, and non-toxic, so it's safe to use on glass or painted panels close-up.

The reversible 2.3mm bullet nib flips to a fresh tip when the first side wears down, and valve-controlled ink flow keeps output consistent from the first mark to the last. A built-in pocket clip keeps it within reach.

Weather resistant against rain, sunlight, and other harsh outdoor conditions, indoors or out, rated for use from 32°F to 100°F (0°C to 38°C) on glass, painted metal, and aluminum. Available in 13 colors, including 6 fluorescent shades (12-unit minimum per color), for eye-catching pricing and promotional displays. Store above freezing to keep the formula from thickening.

Frequently Asked Questions

How do I remove the marking when I'm done?
Wipe it away with an ammonia-based glass cleaner, no scraping or scrubbing required.
Will the marking wash off in the rain or at the car wash?
