Got a new drill bit and finished drilling, countersinking, and screwing all the holes on this thing minus the top which is still in question.
I had 2 blow outs. Not bad for over 250 holes. They are both near the top of the tank and will be filled in the 2 part epoxy and sanded flat before it gets painted and water proofed.
As far as waterproofing goes. I just ordered 1 gallon of Black - Rubber based pool paint from my local ace hardware for 40 bucks. Any other color was 5 dollars more but I wanted the black though so worked out nicely. The pro paint shop in town has the same product but sells it for 65 a gallon and would charge me 30-40 dollars shipping on any special orders. No such fee from Ace. Gotta love that.
It should be here Thursday which gives me lots of time to finish out my sump and get it ready for the test waterproofing and fill.
