General facts about our product line:
To ensure product performance, apply to clean, residue free surfaces. If there is any doubt that the cleaner you are using does not leave surfaces residue free, simply rinse the cleaned surface with rubbing alcohol.
None of Sentry's products are permanent coatings. Each product bonds to the metal surfaces to which it is applied. It will eventually wear off and may be removed using products such as gun solvents or industrial cleaners.
Sentry's product line is based on dry film technology except for HIGH-SLIP GREASE™ which utilizes solid lubricants but remains wet.
All the products last a very long time. You'll get the best performance if you apply a single, thin coating.
SMOOTH-KOTE ™ needs to be stirred and then shaken very well before use.
Questions about TUF-CLOTH ™:
· How often do I need to use TUF-CLOTH™?
When you first start using the product, use it every time you use or handle your equipment. This will ensure that you are getting complete coverage and that TUF-CLOTH's ingredients are able to get into the pores of the metal. Once your equipment has been thoroughly wiped with TUF-CLOTH™ the protection can last several weeks or longer. If your firearm or equipment is exposed to wear or extreme conditions you should use TUF-CLOTH™ more frequently.
· Will TUF-CLOTH™ remove rust on my equipment?
No, TUF-CLOTH™ is not a rust remover. You can use TUF-GLIDE™ on some synthetic steel wool to remove surface rust. If the metal has severe rust you will need to use a rust remover (we find that naval jelly works well). Please keep in mind that rust removers may also remove finishes from metal. Once you have removed the rust, use TUF-CLOTH™ to keep the rust from forming again.
· What if my TUF-CLOTH™ dries out?
No problem, you can use pure, odorless, mineral spirits (available at most hardware stores) to restore the cloth or use TUF-GLIDE™. Simply open the ziplock on the bag and pour about a teaspoon of mineral spirits onto the cloth and re-seal the bag. TUF-CLOTH™ is user adjustable; the wetter the cloth, the thicker the coating. You can allow the cloth to dry in order to apply a thinner coat. A dry TUF-CLOTH™ can be used as a polishing cloth. If you prefer using a wetter TUF-CLOTH™, after the surface is dry you can buff off the excess with a clean dry cloth.
