## Overview

Rust-Block by Evapo-Rust is a revolutionary water-based rust inhibitor that offers up to 12 months of protection on all ferrous metals. Its non-toxic, biodegradable formula is safe for use on auto parts, tools, and garden equipment without the need for protective gear. Easy to apply via spray, wipe, or immersion, it dries to a non-tacky film that rinses off effortlessly with water, making it perfect for professionals and enthusiasts seeking long-lasting, eco-conscious rust prevention.

## Description

RUST-BLOCK™ is a revolutionary water-based rust inhibitor that works on all ferrous metals and is ideal for home or shop use. Rust Block is a specially formulated water based rust inhibitor designed for long-term protection and easy removal. Rust block can be applied through immersion, spray or wipe. It dries at the same rate as water leaving a thin non-tacky film that inhibits rust for up to a year. Treated parts must be stored indoors. Rust Block is removed from parts with a simple water rinse and does not require a chemical cleaner or solvent. This product contains only biodegradable surfactants. RUST-BLOCK™ prevents your items from rusting for up to 1 year. Use it to protect your tools, auto parts, hardware, gardening gear and more. Also, it is ideal for industrial use. RUST-BLOCK™ is non-corrosive, non-flammable and biodegradable. When you are ready to remove the invisible coating, simply rinse it away with warm water. Then, your item is ready to paint, primer or oil.

Review: I sanded and sharpened my Stanley #4 plane iron, and rinsed it with warm water. I then sprayed Rust-Block on both surfaces and allowed it to dry. I stored the iron away in a dry place, and as you can see from the picture, there's ZERO rust. However, I recommend it only for protection against rust while waiting for spray paint or other types of finishing. As soon as you have a little moisture (even your sweat) on the surface, you've essentially removed the layer of protection and rust will start building up really fast.

If you order this at midnight after working 70-hours a week for months you might miss the fine print just like I did. I was wondering why the product didn’t remove the rust as well as the little bottle I had previously used as a test. Thought it might be a different concentration. Never thought I bought the wrong product. Spent hours soaking, removed some of the rust with brushes and sandpaper. Finally gave up and just painted as-is with rust. My garden flamingo project ended up costing over $150 and still not rust-free - when I probably could’ve bought a new one for $200. And I would’ve saved hours of free time of which I have so few. The product is probably great at what it’s meant to do, thus the 5 stars. I’m not penalizing the company for my mistake. Probably good idea to wear gloves but I didn’t and my hands are fine. If the manufacturer is reading this, you may want to use a different color on the bucket and label as it’s virtually identical to the rust remover product.
