I got the Kit 1, with 2.5oz of B2 sealant, labeled NSL brand. While I was dreading the project of fixing my fuel leak, this stuff is actually not bad to work with. It doesnt have a strong smell, and the mess is very manageable if you leave the back cap on and use the included applicator tip. Any excess sealant on the aircraft can easily be wiped away with acetone prior to full cure after that, use Poly Gone. Theres no need for a caulking gun or the sealant mixer tool that goes on a power drill. When freshly mixed, you can squeeze this out with just thumb pressure on the back. When you cant reach any further, push with a deep socket. Throughout the 2hr application time, the sealant will get harder, so if you think youll need that full time, squeeze it out into a paper cup and use popsicle sticks instead.
Dang, this stuff is easy to use,,, and works well in any caulk gun.
My kit came with a nozzle, just FYI for future customers
This is the perfect size for a tank leak repair. The mixing is almost automatic so you get a reliable cure. Ships fast and is worth the price.
Worked great.. less mess.. easy to mix.. works in normal caulk gun as well! BONUS!
Highly recommend this product for sealing exterior pin holes on fuel bladders. Material can be applied on vertical surfaces and does not run or sag. Comfortable working time on previously prepared surfaces. Product has excellent surface bonding characteristics. Product appears to be resistant to ethanol blended fuels. Advise doubling recommended curing times
Fast Delivery, shame the freight is so expensive.
Perfect for sealing our fuel tank fuel level float and attached fittings. Long work life as advertised
Easy to mix without the use of special tools. I pushed the product out of the tube using a socket and extension as a pushrod. The Class B2 has a working time of 2 hours and a cure time (at 77 deg F and 50% RH) of 72 hours. Product worked as expected and seems to retain a little flexibility.
Great product, works as described

Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base.

It has a service temperature range from -65*F (-54*C) to 250*F (121*C), with intermittent excursions up to 275*F (135*C).
The tech data sheet only refers to aviation and jet fuel. It has been used in race vehicles that use many alcohol type additives without any known problems, but the supplier will not recommend it since it has not been lab tested.
The shelf life is 9 months from date of packaging.
It will be flexible when cured, but we recommend verifying with the bladder manufacturer this material can be used.
Per our product support manager: The user would have to pump and twist the ram manually by hand. The mixing tool saves a lot of time and effort.
Proseal has been used in ethanol applications, but the manufacturer has no documentation to provide to show how well, or how long, it will work.
This will adhere to a plastic tank but will eventually breakdown because of the gasoline. This is mainly used for aluminum and titanium steel. This would not be recommended per supplier for a plastic tank.
After the cartridge has been mixed, you can use a manual dispensing gun, p/n's 12-38520 or 12-38530, or an air-powered gun like 12-02923, 12-02922, 12-02921, or 12-02920. A Semco, or other common caulking gun is not designed to be used with these sealant cartridges.
It is self contained, and designed for a one time use. The two parts, A&B, are already properly measured, so the two parts are mixed in the cartridge until one uniform color and then you install the nozzle, and push rod, then just apply to the area.
This will all depend on how thick you are applying this. However there is a formula that will help, if you apply this to an area that is 1" cubed so 1" length x 1" height x 1" depth, it would use exactly 1.8047 fluid oz.
