spoon Posted November 30, 2009 Report Share Posted November 30, 2009 make sure the poly is completly dry and clean the glass first then leave for at least a day before you fill up the tank or longer if there is really thick areas of silicone Quote Link to comment Share on other sites More sharing options...
Barrie Posted November 30, 2009 Report Share Posted November 30, 2009 make sure that the silicone is suitable for both surfaces A lot wont be Dow Coreing 782 should be OK if you can get it Quote Link to comment Share on other sites More sharing options...

scrabble Posted November 30, 2009 Author Report Share Posted November 30, 2009 hmm thanks - I am assuming that I can only clean the glass with warm water - ie no soap or window cleaner???? Quote Link to comment Share on other sites More sharing options...
Barrie Posted November 30, 2009 Report Share Posted November 30, 2009 you can use steelo pads as well I mean steelo, not the brass ones. The steel wool is fine enough to not damage the glass. I take it that your tank will be empty? if thats the case, I would use the soap impregnated steelos but make sure you remove all the soapy water afterwards and rinse a few times befor leaving to dry and glueing Quote Link to comment Share on other sites More sharing options...
