Ducksta Posted March 28, 2004 Share Posted March 28, 2004 OK, I want to reseal a tank. So I have been trying to remove the old silicone so as to not interfere with the adhesion of the new stuff. I have been going at it with a razor/stanley knife but it doesn't seem to be getting me anywhere. So what is the secret? There must be something I am missing. (I bet it's really obvious) Link to comment Share on other sites More sharing options...
anchar Posted March 28, 2004 Share Posted March 28, 2004 Ducksta, Use the double honed industrial blades...you'll need a few because they lose their edge very quickly. The glass may be permanently etched if the silicone has been there for some time. merjo Link to comment Share on other sites More sharing options...
trofius Posted March 28, 2004 Share Posted March 28, 2004 i agree I use the /paint stripper disposable razor type blades from a hardware , it gets almost all of it of except maybe soem residue, to remove this I use a course rag an terpintine and rub real hard , it should just ball up like rubbing your hands together! then i rub down the area with methelated spirit to remove the terps residue, and then rub down with a clean rag and water to remove any metho residue, let dry start siliconing!

CThompson Posted March 28, 2004 Share Posted March 28, 2004 It is a very simple job. Don’t use terps, or acetone. Take off as much as you can with a blade, then use steel wool and metho. Craig Link to comment Share on other sites More sharing options...
agro77 Posted March 28, 2004 Share Posted March 28, 2004 Rasorblade and metho with steel wool, be carfule not to cut yourself, most tanks dont have beveled edges.... Anthony Link to comment Share on other sites More sharing options...
Ducksta Posted March 29, 2004 Author Share Posted March 29, 2004 Well I had a good crack at it this morning with razor/steel wool/metho. Got it all nice and clean, then got to resealing it. This is the part where I cross my fingers and pray Link to comment Share on other sites More sharing options...
CThompson Posted March 29, 2004 Share Posted March 29, 2004 Rest the broken tank on a flat surface, and the replacement glass in position but lying flat on the floor in front of the tank where it is to go. Put the silicon on the replacement glass, then raise the glass with the bottom edge as a pivot point, and put into position. Keep a rag and metho nearby to get it off your fingers and remove it from areas of the tank your silicon fingers have put on the tank in your last seconds of panic. You shouldn’t need to tape the new glass in place, but it wouldn’t hurt to keep some handy. The biggest trick will be to make sure when you raise this new glass into position, that the bottom and top edges are on line with the existing top and bottom edges of the existing tank.
