CS3204 is a fuel resistant sealant for use on integral fuel tanks and pressurized cabins as well as other areas subject to contact with aircraft fuels, lubricants, oils, water and/or weathering.
Had a leak in an integral aluminum fuel tank that hadnt been sealed properly since built. Worked superbly.
Used sealant to repair obsolete 30 year old plastic fuel tank
I really like this product. I use it at work on aircraft, and purchased it here to use at home on my airstream trailer renovation.
Worked as advertised. Used the mixing tool in my drill and mixing was easy and fast. So far fuel tank is sealed up tight and nothing leaking. Hope it lasts for many years to come.
Addition... Mixing: I clamped a slow speed drill (pointing up)in my vise and chucked a hole saw (backwards) that had holes that (nearly) matched the plunger handle of the tube. A couple of #8 screws, and I now had a power mixer. Turn on the drill (CW) and move the tube full stroke up and down 50 times (overkill) or so. Dispensing: Like a previous reviewer, I just used a cheap $5 gun.. mine didnt even require making the plunger diameter smaller.. it fit perfectly...
Used this (B-2)for sealing the fuel sending unit into the side of a wing tank. All is well. I would probably use the faster version next time (B-1/2). Cures very flexible, not as hard as Proseal, but it is a polysulfide product (like Proseal) so we will see how long it lasts.
Although I waste more than I probably should, I never have any issues with these kits not curing properly. I bought a cheap caulking gun and ground the ram down a bit on my bench grinder so that it fits the plunger on these tubes. Presto! $5 proseal gun! (use a zip tie to make sure the tube stays anchored in the cheap big-box store caulking gun)
This sealant works awesome. It cures to a hard rubber and really seals. After trying a different sealant and it not working, I was desperate to find something to seal up my fuel tank. This stuff fit the bill and is completely leak free.
...make sure the metal is bare and clean, i had a wing tank neck/nipple that i had to have a welder extended higher to work with my newly built wing tanks, after welding he gave a shot of spray paint on where he buffed the metal. After i threaded the nipple/neck into the top of the wing tank, I smeared the sealant on the inside of the nipple at the junction of the threads in addition to putting sealant on the fine threads. The sealant i had on the smooth part of the inside of the nipple started to lift because of the spray paint the welder put on after welding.
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.
