my friend will drop off a tube of the super black sealent through the mail slot.
it comes with a manual aplicator ,your smart you will figure it out.
remember parts must be put together in 10 min -thats more than enough time for cylinder barrels,
the stuff will keep in the tube just push the hardend tip/sealent out and use again.
caution this stuff bonds better than shit too a wool blanket !!!!
