First of all, I just want to say thanks for all the great comments!
I finally have all the coats on this puppy. I ended up buying another 6L kit of epoxy so it is well and truly sealed. It has now been fiberglassed first followed by 2 coats of epoxy with a good sanding in between. Sanded again and another 3 coats which were applied in succession before the previous coat was cured.
Pics here are with the flash not long after the final coat.
This is the spot it will be going. I will raise it onto the blocks once the glass is in which probably won't be for a few weeks due to prior commitments.
Found my first piece of wood for this tank today. What do you think of this for a center piece? I had to get wet for this one
I will cut the upright piece so it wedges under the cross support. And yes, it fits through the top openings. Just
