Finished sealing up the right tank. I mixed up 200 gms of sealant using the bag method again. This time, I put the bag inside the cup, draping the top of the bag around the top rim of the cup. This was then held in place on the outside of the cup with a rubber band. I measured out the sealant into the bag an mixed with a popsickle stick. Finally I took the cup away and sealed the bag up with the zip lock. This worked really well. Cut a small hole in the corner of the bag and squeezed out sealant as needed.Both tanks are now closed up ready for leak testing.
