## Overview

## Description

Product Description METAL EFFECTS PRIMER (Formerly Acid Block): A unique water based, acrylic primer designed to block Patina Aging Solutions and Rust Activator from reaching the metal or wood surface chosen as a substrate. Other primers cannot be used because they allow the Patina Aging Solutions and Activators to penetrate through to the substrate. This will disrupt the desired patina color and damage the finish by bringing rust or tannic acids to the surface. ~~~ FEATURES: Unique water-based acrylic prime, Blocks Patina Aging Solution from surface. For use with Modern Masters Reactive Metallic Paints. Other primers cannot be used. Covers 2. 5 sq. ft. per 4 oz. Primer Rust Red. From the Manufacturer A unique water-based, acrylic primer designed to block patina-aging solutions and activators from reaching the metal or wood surface chosen as a substrate. Other primers cannot be used because they allow the patina-aging solutions and activators to penetrate the coating.

Review: You DO need the primer with the reactive paints. - I didn't think I needed the expensive primer to go along with the reactive paints in this line, but got in anyway just in case. I'm glad I did. The bronze and the copper paints are very thin and you won't get any coverage without the primer. The primer provides a slightly toothy texture for the metal paints to grab onto, and the primer paint itself is very "grippy." I've used it on mason jar lids, glass jars, an old wooden picture frame, an ugly metal lantern, two glossy cheap plastic/resin birds, and a cheap base metal box. The primer did well on all of those surfaces. The paint goes a long way, and even though you do need two coats, two thin coats is sufficient. I've used about 1/8 of the 16 ounce bottle after all of those (albeit small-ish) projects.
Review: Fantastic stuff! - I have re-ordered this item 3 times because I go through it so fast. It is great for rusting metal. It is the primer that protects the metal before you rust on metal. It is essential and a great product. If you’re going to be resting any type of metal, you’re going to need this product.

### ⭐⭐⭐⭐⭐ Excellent results. Bought iron wine rack at flee market ...
*by B***L on January 5, 2017*

Excellent results. Bought iron wine rack at flee market and needed TLC. Could not be happier with results. Started with blocking primer followed by MM's bronze reactive metallic and finished with green aging solution. The patina is extremely natural and the overall results exceeded my expectation. This a great set of products that actually deliver the promised results.
