ALUMA-HYDE® II Reviews & Ratings

ALUMA-HYDE II

The special feature of Aluma-Hyde II (and the reason for its development) is its increased resistance to bore cleaners, solvents and other cleaning chemicals, even trichloroethylene. Today’s family of fast, aggressive bore cleaners really do a terrific job getting dirty gun bores sparkling clean, but they can wreak particular havoc with any other finish they contact. After full cure, Aluma-Hyde II proved solvent-proof to all but the most aggressive, copper-removing bore solvents. Aluma-Hyde II is formulated with a hard-curing epoxy base that contains additional, high-density pigment for a durable finish that sticks to all properly prepared aluminum and alloy surfaces, steel and plastics - it’s great on synthetic stocks. Aluma-Hyde II is available in a variety of colors to help the gunsmith match the vast number of applications found in the average gunshop. Aluma-Hyde II dries to the touch in only minutes and reaches full cure in about a week. Absolutely no primer coat is required for a tough, durable, abrasion-resistant, rustproof finish that blends beautifully and compliments all gun finishing applications.

Each can of Aluma-Hyde II is now supplied with a Clean Out Nozzle, required to be used before each use of the paint to prevent clogs in the Nozzle and Pickup Tube. Aluma-Hyde Clean Out Nozzles allow nearly unrestricted pressure to flow through the pickup tube and nozzle to clear out any semi-hardened paint that may be in the pickup tube. Once clear, replace with the original spray nozzle and start your project. When used correctly, this will ensure a smooth, sputter free paint application free of clumps or inconsistencies.

Additional Clean Out Nozzles can be purchased as singles, 430107431, or in a 12-pack, 084179004. Clean Out Nozzles are not intended for finish spraying.

SPECS: 12 oz. (340 g) aerosol can.

INSTRUCTIONS:

PREP THE SURFACE: NO priming required on clean, bare metal or anodized surfaces. Surface should be dry and free of oil, wax, dirt, loose paint, and any other contaminants. Painted surfaces should be washed with a cleaner degreaser. If cleaning parts with abrasive blasting, make sure blasting media is oil- and silicone-free. Test a small area for color compatibility and adhesion.

• Unpainted aluminum: Abrasive blast to achieve desired surface look/texture.

• Unpainted steel: Remove rust by sanding or abrasive blasting.

• Fiberglass: Sand lightly, then wash with soap and water or clean with a quality cleaner degreaser.

• Wood: Seal or fill surface. ALUMA-HYDE II can be applied over polyurethane and varnish finishes but not over linseed oil or tung oil finishes.

PREP CAN: For best results, use between 70° F and 90° F (not below 65° F). Shake can vigorously until the ball inside rattle; then shake for 2 minutes more to achieve correct color and texture.

INITIAL CLEARING SPRAY: Before spraying work surface, point can in safe direction and depress valve. Press until spray is consistent in color and consistency. The cleanout nozzle can be used in this step for previously used, or even new cans. The cleanout nozzle is used to ensure any residue or buildup is easily ejected from the can. Simply pull the standard nozzle upwards off the can and press the cleanout nozzle down in its place (be careful to point can in safe direction when pressing downwards, as can may discharge spray).

Cleanout Nozzles are included with each can of Aluma-Hyde purchased from Brownells and is available separately. Search item number 430107431.

SPRAY IT ON: Hold can approximately 12” away from the work surface and fully depress valve on top to start the spray. Shake can periodically during application process.

LET IT CURE: This is a critical step in getting a truly tough, long-lasting finish! If a second coat is needed, it should be applied within 30 minutes. After 30 minutes, Aluma-Hyde II must be allowed to cure 10-14 days before recoating.

• Dries to a light touch in approximately 10-15 minutes. Wait 24 hours or more before extensive handling.

• Complete cure time caries depending on film thickness, temperature, and humidity

• Cure time can be reduced by circulating warm air (90°F max.) or placing part in direct sunlight.

• Aluma-Hyde II can be “speed cured” by baking the part for 3.5 hours at 195°F. Allow part to cool before applying another coat.

Awesome, but…

This is as close to cerakote as you will find without all the mess. Brownells hear me!! Make more colors!!! PLEASE!!! The difference between FDE, Coyote, and earth brown is negligible. So make some more colors maybe a greener green and a burnt bronze please.

Good paint

I’m kinda new to this paint but it seems to be working well so far. Had one tiny little piece flack off Pmag but it could have been prep failure. Time will tell!

Awesome on anadized.. Raw no

I have painted several firearms with Aluma-hyde. If the anadized surface is there it sticks amazingly. I had a handguard that was cerakoted, and had to remove it because you can't paint over it. The Aluma-hyde went on good, but I find it chips easily when applied to raw aluminum, especially on edges.

I love this stuff but dropped a star because of color discrepancy.

I love Aluma-Hyde, it comes out perfect as long as you follow the suggested prep and application process. I’ve used the ODG, Magpul FDE, Coyote, and Earth Brown. Each have always come out lighter than the shade on their caps. The FDE is far too llight to match Magpul’s. The Coyote is closer to FDE but still a shade lighter. My favorite and best results are with the Earth Brown. It’s a shade darker than FDE but nothing close to its dark brown cap. It’s closer to Aero’s FDE.

Wish you had more instructions

Wish you had more instructions on the usage sheet about cleaning the spray nozzle or the need to buy additional nozzles. Nozzle plugged up and caused spattering and runs. Had to sand and respray. The Aluma-Hyde itself is GREAT!!

Great product but very temperamental

Steps to get a good finish when using this product. 1. Steadily shake the cam for at least 10 minutes prior to use. The hardener will separate if the product sits for more than a few minutes. You gotta shake it up for a while or your first several sprays will be nothing but hardener, and look like you spilled syrup over wjat you are painting. 2. Use paint thinner, lacquer thinner, brake cleaner, acetone, etc. on the spray cap after each use. Do this even between applying coats. If you don’t, the epoxy will clog up the spray cap and you will get a jet stream coming out of the cap on the next application. Do this EVERY time. This issue could be solved if Brownells didn’t use the cheapest spray caps out there.

Works. Used 3 times successfully

I've used this Aluma-Hyde II stuff on 3 different rifles. 1st go around was a bit of a learning curve. If you cant bake it, be prepared to wait about a week to cure. Very first use was a number of years ago on a Savage Mark II FVSR. Still holding strong. Used on another reconditioned .22 and an AR since. Only used matte black.

Can be great but you need to know what your doing.

Have used it a few times to coat my AK, AR and my G3A3 clone. If used properly with light-medium coats and given time to dry after baking it create a very good durable coat. However if you don't know what you are doing you will have to spend quite a bit of money to get a professional to fix your gun then even more doing a new coat.
