Depending on the leak and the condition of the gasket. Permatex® offers the Form-A-Seal® Leak Repair product. It is an aerosol product designed to form a durable rubber barrier that stops leaks in minutes without having to disassemble the parts.
As with our ULTRA Gasket Makers, OPTIMUM Gasket Makers are RTV silicones that require 24 hours for a full cure. The RIGHT STUFF eliminates the need to wait for the gasket maker to cure – just torque and go! The elastomeric technology used in The RIGHT STUFF is heavy bodied with 10 times the density of our ULTRA and OPTIMUM products. It delivers a blowout resistant, heavier and faster sealing bead, outperforming pre-cut or traditional gaskets while offering immediate return to service. Proven effective over millions of miles of fleet testing, The RIGHT STUFF will continue to be the professional’s choice when time is of the essence.
OPTIMUM BLACK combines maximum oil resistance with high flexibility. Today, we see components changing and unlike materials meeting (plastic/steel, aluminum/steel, etc.), all with different rates of expansion and contraction. In addition, with technology advancing, regulations and requirements tightening, we see thinner metals, fewer fasteners, and wider spread bolt patterns. The strength and flexibility of OPTIMUM BLACK handle the changes and added stresses that exist between today’s lightweight, high performance, and premium component assemblies. It is sensor safe, low odor, and non-corrosive with resistance to oil, shop fluids, and vibration.
Use on newer lightweight and premium components where maximum oil resistance is required. OPTIMUM BLACK is best for assemblies where dissimilar materials meet. Application examples include valve covers, oil pans, oil pumps, intake manifold end seals, and timing gear covers.
OPTIMUM BLACK is up to 60% more flexible and 15% stronger than ULTRA BLACK while maintaining maximum oil resistance through the use of a patented adhesion system. The strength and flexibility of OPTIMUM BLACK allow for dynamic changes in today’s lightweight, high performance, and premium component assemblies. Also, an extra nozzle is included adding convenience.
OPTIMUM GREY combines maximum torque load and vibration resistance with extreme temperature resistance: -65°F to 700°F (-54°C to 371°C) intermittent, expanding uses and applications. This feature combination joined with outstanding resistance to oils, coolant, and shop fluids make OPTIMUM GREY one of the most versatile gasket makers available. Also, an extra nozzle is included adding convenience, eliminating the hassle of a clogged nozzle, and allowing multiple uses of each tube without loss of product.
Use on high-torque, high vibration, and high temperature applications, like those common in import & late model engines and component upgrades. OPTIMUM GREY is best for assemblies where high temperature and high vibration exist. Application examples include valve covers, intake manifold end seals, timing covers, water pump and thermostat housings, exhaust manifolds/headers, and slip-fit exhaust parts.
OPTIMUM GREY is up to 15% more flexible than ULTRA GREY and delivers 40% higher temperature resistance while maintaining outstanding resistance to oils, coolant, and shop fluids. OPTIMUM GREY combines the maximum torque load and vibration resistance capabilities of ULTRA GREY with the maximum temperature range of ULTRA COPPER: -65°F to 700°F (-54°C to 371°C) intermittent. These feature combinations expand uses and applications making OPTIMUM GREY one of the most versatile gasket makers available. Also, an extra nozzle is included adding
Permatex® does not suggest adding any solvents, chemicals or fillers to any of or products that will change their formulas, characteristics or the way that the Permatex® product was designed to perform. Permatex® offers many other products that may work for your application. You can contact the Permatex Tech Center at 1-877-376-2839 and, if you give them more information, they will be able to help you select another product that might work for your application.
The Ultra Copper® is a silicone product and is copper in color. It does not contain any copper or other metal and it is not electrically conductive. For additional information, go to the Ultra Copper product page and view the TDS.
No, Ultra Blue® is a silicone-based product, that will offer a good seal, and has good resistance to oil and coolant, however, silicones are not recommended for use in a gasoline environment. The gasoline will attack the product. Permatex® offers the solvent based Form-A-Gasket® products or MotoSeal® #29132 that are designed for applications in a gasoline environment.
The Aviation Form-A-Gasket is a slow drying, non-hardening, sealant, resists gasoline, oil and grease. It is used for close-fitting machined surfaces, sealing hoses and solid gaskets.
Form-A-Gasket® #1: fast drying, hard setting, designed for rigid materials and flanges. Form-A-Gasket® #2: slow drying, non hardening, designed for sealing cut gaskets on non-rigid, vibrating, stamped parts, allows for easy disassembly if required.
Permatex® does not recommend the use of any anti-seize product on wheel studs. Many people have used anti-seize for this applications, however, there is the potential for over-torqueing and therefore, higher clamp loads and potentially dangerous bolt stretch. Because of the lubricity of anti-seize, there is a tendency to over-tighten because of the ease with which the nut will bear down on the lug. For this reason, even if you try to torque the nuts to factory specs, the clamp load may become too high depending on the type of bolt, size and manufacturer.
Permatex® does not suggest using Rust Treatment for this type of application. It may cause blistering or peeling of the paint.
Once the buttons are bonded in place they are very difficult if not impossible to remove. Prying or heating the button will damage the glass. The best thing to do is to bring the mirror head to the local Automotive Parts Store or Automotive Dealer and have them match the mirror to a new replacement-mounting button. Then purchase another Permatex® Rearview Mirror Kit and mount the new button correctly on top of the button that is currently bonded incorrectly to the glass.
The plastic sheets (yellow or clear) are curing strips that are used to cover the adhesive that was placed in void or crack of the windshield to shield out the air so the anaerobic adhesive will cure or harden.

The Surface Prep Activator is suggested for use on inactive surfaces and it can be used to accelerate the cure time for anaerobic products applied to active surfaces. The product is also a general purpose solvent for cleaning and preparing parts and surfaces.
Apply heat 450F+ to the parts and remove the fasteners when hot.
The different colors indicate the different strengths of the products. Purple = Low strength, Blue= Medium Strength, Red= High Strength (other colors indicate different strengths for various applications).
The Threadlockers were created for different sealing and locking applications. Permatex® offer Threadlockers for small screws up to large diameter bolts, removable and permanent assemblies, high temperature applications and threadlockers for assembled and pre-assembled applications.

All Permatex® products are stamped with a date/batch code number indicating when the product was made. Here’s an example of the date code and how to read it (Example: 9AB1234A01) the first digit is the year 1=2011, 0=2000, 9=2009 etc. and the first letter is the month of the year A=Jan. B=Feb. C=Mar. etc. the next letters and digits is the batch number and the last two digits in the day of the week the product was manufactured 01=1st-31=31st. The example: 9AB1234A01= 9=2009 A=January 01=1st day of month.
