I just finished the last step and poured the sealer into the tank. Swriled it around, let it sit on every concievable side and coated every inch giving it a thick opaqe cover. Then when I let it sit for about 10 minutes, the vertical walls become translucent as the materal flows down. So I rotated the tank again, and again, and again. 3 hours later, it’s still becoming translucent. I thought there wasn’t enough material to cover the 16 gallon tank, but when I finally drained it, I got 1/2 a bottle full. A few hours later, the sides are still translucent, but now I have heavy drip marks on the sides. So I have a few questions:
1) Do I have sufficient coverage on the sides?
2) Will the drip marks pose a problem? and,
3) Does the sealant dry hard or stay semi flexable?
