Per the vendor, if it is used shortly after purchase, part number 09-03477 should not need anything to thin out the product. Make sure it is well mixed and it should be fine without any additional products.

This sealer is only recommended for metal or fiberglass fuel tanks.

This is a tricky question. Yes it should work, but there are no specific tests done with any specific epoxy or resin system used to make a fiberglass tank. As long as the tank is cleaned and prepped properly, it should work just fine.

Per out product support manager: it is a sloshing material that will fill small pin hole leaks and seal the inner tank. It can be poured in and sloshed around in a fuel tank.

Per the supplier: this product has a 2 year shelf life that starts once it is opened.

Per the manufacturer: The entire interior of the tank must be dry. If only one small area of the tank is not dry or has foreign matter that may keep the sealer from adhering, the sealer will not stick to those areas and could come loose and float around in your tank and eventually come through the fuel pick up tube and clog the fuel pump and carburetor. The solvent for this sealer is methyl ethyl ketone (mek). Before introducing any additives to fuel tank after sealer has been installed, be sure that the product you introduce does not contain (mek). (mek) can soften and loosen the sealer which in turn can clog your fuel lines, carburetor, etc. Avoid using "gumout" or similar products which have been known to use (mek).

The 09-03477 is a sloshing sealer that gets poured in a fuel tank and the tank rotated so the material gets on all parts of the tank. The 09-38560 is a much thicker material and requires a brush to spread the material.

The primary purpose of this material is to coat the inside walls of a fuel tank for protection. It is a pour in and slosh around material. I could not find any information as to how well it would work if brushed on, or what size pin holes, or rivets, it would seal.

This is a single stage component. There is no thickness that we recommend. Each application can vary. The product generally leaves behind a very thin coating. It is not supposed to be very thick. The idea is to pour the product in to the tank and slosh it around. Once all of the walls of the tank have been hit, they customer should drain the remaining sealer out back in to the can. There should be no puddling of the product as this will prevent it from drying properly. If the customer wants to do a 2nd coat after 24 hours with the remaining product, that is fine. This is only needed if for some reason they missed a spot during the initial application. A thicker coat or 2nd coat really won't offer any added benefit in terms of protection.

Yes, this is considered hazardous material. For ground shipping within the USA there is no hazmat fee, but for any shipments, it will incur significant hazardous charges.

It has a pretty long working time. It's designed to be sloshed in the tank and then the excess is poured back in the can. It doesn't cure for 24-72 hours after that.

Yes this sealer can stand up to diesel fuel, the issue will be in the prep work before applying the sealer. The tank must be 100% cleaned. No residue can be left or the sealer may not stick as the diesel has an oil mix in it that can be difficult to remove when the tank is empty. Boiling out the tank, or a thorough cleaning with a strong cleaner de-greaser , like ours, will do the job.

Per the vendor, this would not work for this application. It does not have heat rating.

The manufacturer recommends paint remover or MEK.

Yes you could drain the tank and reapply.

No this will not stay flexible after curing.
