I was just trying to avoid purchasing a gram scale because pre-measured is seemingly easier. Plus, I can just hear it now Did you hear about that guy with the pony tail down at hangar 45? Airport security found him with a gram scale and two large bags of white powder. Honest officer, its only micro balloons and flox.
We used syringes to measure out the correct volume for proseal.

Default Measure tank sealant by weight

Alex - Obviously measuring by volume worked OK for you.

However, the product application data sheet does say to measure the two components by weight.

resurrecting an old thread regarding the 12iS tank..

you will need 3 batches -- two for the tank and one for other things (fairings, etc).

The instructions call for you to familiarize yourself with the build and says you'll need 3 hours of uninterrupted work for the tank. I found that to be true (even with rehearsing the build and working without any delay).

In 2 hours, I was only able to finish the top half of the tank (excluding the main access hatch and the two boomerang doublers on the side of the tank (12iS)).

I had a 6oz tube which was ample. After 2 hours, I probably still had 2oz unused.

If I had a helper who could dip the rivets for me and another that did clecos, I probably could have finished the tank in one session .. and in that case, I'd recommend 1 6oz tube.

For solo work, I'd recommend three of the 2-hour 3.5oz cartridges

Ok, so I'm just starting my wing kit, so rather nave regarding fuel tank sealant, which I see I will need to seal the position lights to the wing tips too. Can someone explain why one of the many "single can" fuel tank sealants on the market, like this one

https://www.amazon.com/dp/B00B3HXCZ4...v_ov_lig_dp_it

can't be used vs. two-part mix Proseal? Appreciate the education.

Did you read the info on it? Might be a very good product, but it's effectively a 'slosh' - applied sealant for old corroded tanks. Sloshing sealants have a really bad rep around RVs. I'm not in the camp that thinks it's all the sealant's fault, but I'm sure I'm in the minority.
