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.
Lubricants
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.
Specialized Maintenance
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. For more information click here Windshield Repair Video to view a how-to-use video showing tips on how to use the product.
Thread Compounds
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.
Miscellaneous
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.
