Is there a way to take this apart to get to components out without contaminating the sealant with the hardener?
Vans Flamemaster Fuel Tank Sealant
Reason is I need two or three sessions of maybe a fourth or less. I don't want to buy several tubes. I have one fresh one in the freezer.
If it's possible, I'll transfer to tiny metal paint cans

 

[David Paule]

Yes.

Carefully disassemble the device and transfer the contents to clean containers that seal well. It's a bit awkward and can be messy but works. I've done it.

Caveat, I did it several years ago and this is all from memory.

A pint?

If you're willing to fork out extra $19 then that will buy a pint in a can. Any unused can be kept in the freezer for ages and may save you forking out $21 in future for another little bit.
This is by the same manufacturer as Vans stuff.

Any time I need to make a Spruce order there's always a few screws, hardware etc that can ship for the same postage.

Thanks Dave, I will try that first.

Shoulda, woulda, coulda!
That's what I should have done. Maybe what I will end up doing!

My 2c, this is the only product I will use in tanks.

I used that 890 sealant and it failed and reverted to goo so the tanks needed to be completely cleaned and re-sealed. In my experience the 890 was no better than the CS3204 and yet it is more expensive. There is a mil spec for the polysulfide sealants.
