Mastercoat® Hot Jet Ceramic High Heat Coating for Manifolds & Headers Polished Aluminum 4oz & 8oz Bottles

An 8 ounce bottle will coat one set of shorty headers.

A 4 ounce bottle will coat up to 4 manifolds.

Description:

FOR POLISHED ALUMINUM VARIETY ONLY: A high heat coating containing aluminum powder in an inorganic binder. This coating will air dry but can also be oven cured at temperatures of400°F up to 650°F. This coating is ideal for headers and exhaust manifolds. It also can be used on steering boxes, calipers, and any other parts where a polished aluminum look is desired.

Surface Preparation

Special care must be exercised in the preparation of the surface for all high quality, premium performance coatings. 1.) Degreasing. After sandblasting, it’s recommended that a propane torch be passed over the manifolds or headers to bleed any oils from the substrate. This is especially important since this is a water based coating and it will not stick to a contaminated surface. 2.) Cleaning and roughening. All old coats, mill scale, rust, or other tightly adherent deposits must be removed by a method such as a dry grit blasting or vapor blasting. Grit blast, using clean aluminum oxide (AL203) grit, is the recommended cleaning procedure which is necessary for maximum adhesion to steel, although other abrasive methods may be satisfactory.

Application

One coat should be sufficient for protecting the exhaust. Stir product well and spray a very light mist coat in the hard to reach areas and around all flanges or bosses. Then open the fluid flow and quickly spray one wet coat over the entire header. Do the hard to reach areas first as you don’t want overspray from that on the easy to see sections. It is important to move quickly and wet the entire part, but attempt to avoid runs. There shouldn’t be a need for a second coat. Once air dry to a dull gray finish, you can cure them at either 400°F for one hour or 650°F for 30 minutes. Lower temperatures are ok, but it will polish better the higher it is cured. After cured and cooled, you can use 0000 steel wool and metal polish to bring up the shine. It shouldn’t take a massive amount of effort to get some shine, but it will take quite a bit of work to get a very high shine unless you have a vibratory finisher.

Clean Up

Clean equipment using warm tap water.

Coverage

Theoretical coverage is 800 square feet per gallon at 1 mil. dry film thickness.

Removal Of Coating

If it should be necessary to remove the cured coating, it can be stripped by grit blasting or immersing in a hot (approximately 150°F) caustic soda solution. Care should be taken when using a caustic solution since hydrogen will be generated. Area should be well ventilated.

Precautions

Contains aluminum powder dispersed in alkali metal silicate solution. WARNING: Alkali material causes irritation. Avoid contact with eyes, skin, and clothing. Wash thoroughly after handling. Wash contaminated clothing before reuse. FIRST AID: In case of eye contact, immediately flush eyes with plenty of water for at least 15 minutes. Consult physician. For skin contact, flush with water. SPILLAGE: Mop up with water and dispose of in accordance with federal, state and local environmental control regulations. STIR PRODUCT WELL BEFORE USE.
