1. What is the recommended method of Application for Marine use?

An airless spray system using a 517 or a 519 tip at 2500 PSI pressure is the suggested method for Industrial, Marine or Military applications. Three generous coats, properly applied, will achieve the total dry film thickness (dft) of 12 mils as required for surface protection under the 10 year warranty. It is recommended that before and after each coat of Rust Bullet is applied; the pump, lines, and sprayer be flushed with Xylene. It is essential to keep the application equipment clean and the line free of any Rust Bullet product. Acetone may be substituted if Xylene is unavailable.

2. Are there recommendations on Media Blasting?

Soda Blasting and Dry Ice Blasting are two methods of media blasting that are effective, clean, and environmentally safe. Both media are sound options and clean up will be relatively minor including the drying procedure after the dry ice blasting.

3. Is it necessary to remove surface paint prior to applying Rust Bullet?

The removal of existing surface paint prior to Rust Bullet application will depend on the condition and type of paint on the surface. To achieve maximum adhesion, it is always recommended to remove any old paint or coating before applying Rust Bullet.

4. Do I Apply Rust Bullet only where Rust is Apparent?

Rust Bullet is designed to protect rusted and clean metal. It is always advantageous to protect metal, even when there are no visible signs of corrosion. If Rust Bullet is applied only in the rusted areas, it will stop the rust on that surface area, but the uncoated area will be left unprotected. Remember, if it’s made or iron or steel, it will rust and corrode if left unprotected.

5. Are additional coats of Rust Bullet required for Marine Applications?

As Rust Bullet cures it releases carbon dioxide gas while dehydrating the rust. This process of “gassing off” (expelling solvents) may create small pin holes in the first coat of Rust Bullet. A generous initial coat of Rust Bullet will penetrate the rust down to the original metal surface while the second and any successive coats seal these tiny pin holes, forming an air tight, armor like shield over the application surface. If these pin holes are not sealed after the first coat, air and moisture may penetrate the Rust Bullet, allowing rust and corrosion to form.

6. Is there a recommendation of the number of coatings for a ship submerged in Sea Water and what is the effect of salt water on Rust Bullet?

Three generous coats would be the minimum recommended. If the ship will be used to do a lot of hard docking or hard landing on the beach then four coats will provided more adequate protection. Sea temperatures vary as does the salt content and these factors may affect the recommended dft. Salt water should have no effect on Rust Bullet unless the water temperature is rapidly changed from sub zeros to a couple of hundred degrees Fahrenheit. If the Rust Bullet coating is applied properly from preparation to the end, the coating will not peel or bubbling off. Unless there are unexpected chemicals concentrated where the hull is submerged, the Rust Bullet coating should hold its ground with ease. Should there be an event, such as a boating accident and the coating integrity is compromised, after inspection and evaluation, you can always re-apply the Rust Bullet to the comprised area.

7. Does Rust Bullet recommend the use of antifouling paint?

Rust Bullet provides durable surface protection that is scratch, chip, chemical, and UV resistant. Antifouling bottom paints reduce or eliminate marine growth that develops on a boat’s underwater surface. Antifouling paints do this by using biocides (chemicals) that slowly release to repel underwater aquatic life. Most antifouling paints require a chemical reaction with the surface to which it is applied for proper adhesion. This reaction does not occur when applied over Rust Bullet as Rust Bullet is virtually impenetrable. If you do use antifouling paint, scuffing up the Rust Bullet surface along with the use of an etching primer may be necessary. Only use antifouling paint that is compatible with an aluminum hull; that’s virtually what you end up with when a surface is protected with Rust Bullet. Always check with the antifouling paint’s manufacturer before applying an antifouling paint over Rust Bullet.

8. Is Rust Bullet advised for use on Gasoline Tanks?

Rust Bullet is not affected by gas itself; Rust Bullet was not and is not designed as a tank sealer for the inside of a non-commercial small gasoline tank we do not have an official recommendation on this application. Rust Bullet has not been tested for application inside this type of gasoline tank therefore we extend no warranty or guarantee.

9. Can Rust Bullet be applied to an Aluminum Hull?

Yes you can Apply Rust Bullet directly to the clean surface of an Aluminum Hull.

10. Will Rust Bullet reduce the growth of Marine Organisms?

Based on the chemistry of Rust Bullet it is inhospitable to marine organisms. Marine organisms require several conditions to survive; such as sun light, suitable temperature range and a host surface on which to colonize. Additionally, these organisms capture energy from the sun in the bonds of carbon-based molecules through a process called photosynthesis. Rust Bullet has exceptional chemical resistance and forms an armor shield like coating. This shield should prevent any colonization of Autotrophs, such as algae, plants, and some bacteria; however, we cannot say Rust Bullet will stop the growth of marine organism forever, as there are many other factors involved. Such as the ship’s location, length of period at harbor, and travel locations to name a few. An antifouling paint is still a very good application that will enhance the prevention of growth of the Autotrophs, as well as the benefit of additional protection to the ship’s underside.

11. Does diesel fuel degrade Rust Bullet?

Rust Bullet will hold up to #2 Diesel Fuel without issue.

12. Galvanic Corrosion between Two Dissimilar Metals:

Rust Bullet will prevent the chemical action between the two metals.

13. What topcoat can be used on Rust Bullet

Rust Bullet requires no topcoat however the final coat of Rust Bullet can be top coated after 24 hours with most conventional topcoat paints compatible with aluminium surfaces , due to the large number of coatings available it is recommended to check manufactures guidelines and use the appropriate primer where recommended for a particular topcoat. Water based or latex paints are not recommended to be applied directly to Rust Bullet.
