Hey All, I've got a glass tank that needs to be resealed. Its fairly large and I need some tips on how to successfully complete this project. Tank is a 6 footer rimless and glass is 1/2 thick. Heavy as hell! Ive already cut the glass panes apart and now I need to clean the silicon off and clean and prep the glass. I'd like to know.... 1) is there a solvent that will help me remove the old silicon off the glass? 2) what solvent for cleaning the glass to insure oil free surface?
