bought a 180 for cheap and three sides were painted black well when i scraped the paint off there is a crack all the way up one side...I AM PISSED.... my question is i have a piece of glass that will fit over the crack znd cover alot of area but not the whole side if i silicone this piece of glass over the crack will this work or will the tank still fail???? piece of glass is 3/8 tank is 5/8.. i am thinking tha t it might hold but i want to make sure before i do this since removing that piece if glass will suck if it doesnt work...
